==============================================================================
===
=== This file documents the new and/or enhanced functionality added in
=== the Asterisk versions listed below. This file does NOT include
=== changes in behavior that would not be backwards compatible with
=== previous versions; for that information see the UPGRADE.txt file
=== and the other UPGRADE files for older releases.
===
==============================================================================
------------------------------------------------------------------------------
--- Functionality changes from Asterisk 16 to Asterisk 17 --------------------
------------------------------------------------------------------------------
chan_sip
------------------
* The chan_sip module is now deprecated, users should migrate to the
replacement module chan_pjsip. See guides at the Asterisk Wiki:
https://wiki.asterisk.org/wiki/x/tAHOAQ
https://wiki.asterisk.org/wiki/x/hYCLAQ
Channels
------------------
* The core no longer uses the stasis cache for channels snapshots.
The following APIs are no longer available:
ast_channel_topic_cached()
ast_channel_topic_all_cached()
The ast_channel_cache_all() and ast_channel_cache_by_name() functions
now returns an ao2_container of ast_channel_snapshots rather than a
container of stasis_messages therefore you can't call stasis_cache
functions on it.
The ast_channel_topic_all() function now returns a normal topic,
not a cached one so you can't use stasis cache functions on it either.
The ast_channel_snapshot_type() stasis message now has the
ast_channel_snapshot_update structure as it's data.
ast_channel_snapshot_get_latest() still returns the latest snapshot.
Bridging
------------------
* The bridging core no longer uses the stasis cache for bridge
snapshots. The latest bridge snapshot is now stored on the
ast_bridge structure itself.
* The following APIs are no longer available since the stasis cache
is no longer used:
ast_bridge_topic_cached()
ast_bridge_topic_all_cached()
* A topic pool is now used for individual bridge topics.
* The ast_bridge_cache() function was removed since there's no
longer a separate container of snapshots.
* A new function "ast_bridges()" was created to retrieve the
container of all bridges. Users formerly calling
ast_bridge_cache() can use the new function to iterate over
bridges and retrieve the latest snapshot directly from the
bridge.
* The ast_bridge_snapshot_get_latest() function was renamed to
ast_bridge_get_snapshot_by_uniqueid().
* A new function "ast_bridge_get_snapshot()" was created to retrieve
the bridge snapshot directly from the bridge structure.
* The ast_bridge_topic_all() function now returns a normal topic
not a cached one so you can't use stasis cache functions on it
either.
* The ast_bridge_snapshot_type() stasis message now has the
ast_bridge_snapshot_update structure as it's data. It contains
the last snapshot and the new one.
------------------------------------------------------------------------------
--- Functionality changes from Asterisk 16.1.0 to Asterisk 16.2.0 ------------
------------------------------------------------------------------------------
ARI
------------------
* Whenever an ARI application is started, a context will be created for it
automatically as long as one does not already exist, following the format
'stasis-<app_name>'. Two extensions are also added to this context: a match-all
extension, and the 'h' extension. Any phone that registers under this context
will place all calls to the corresponding Stasis application.
res_pjsip
------------------
* Added "send_contact_status_on_update_registration" global configuration option
to enable sending AMI ContactStatus event when a device refreshes its registration.
Core
------------------
* Reworked the media indexer so it doesn't cache the index. Testing revealed
that the cache added no benefit but that it could consume excessive memory.
Two new index related functions were created: ast_sounds_get_index_for_file()
and ast_media_index_update_for_file() which restrict index updating to
specific sound files. The original ast_sounds_get_index() and
ast_media_index_update() calls are still available but since they no longer
cache the results internally, developers should re-use an index they may
already have instead of calling ast_sounds_get_index() repeatedly. If
information for only a single file is needed, ast_sounds_get_index_for_file()
should be called instead of ast_sounds_get_index().
Features
------------------
* Before Asterisk 12, when using the automon or automixmon features defined
in features.conf, a channel variable (TOUCH_MIXMONITOR_OUTPUT) was set on
both channels, indicating the filename of the recording.
When bridging was overhauled in Asterisk 12, the behavior was changed such
that the variable was only set on the peer channel and not on the channel
that initiated the automon or automixmon.
The previous behavior has been restored so both channels receive the
channel variable when one of these features is invoked.
app_voicemail
------------------
* You can now specify a special context with the "aliasescontext" parameter
in voicemail.conf which will allow you to create aliases for physical
mailboxes.
------------------------------------------------------------------------------
--- Functionality changes from Asterisk 16.0.0 to Asterisk 16.1.0 ------------
------------------------------------------------------------------------------
pbx_config
------------------
* pbx_config will now find and process multiple 'globals' sections from
extensions.conf. Variables are processed in the order they are found
and duplicate variables overwrite the previous value.
chan_pjsip
------------------
* New dialplan function PJSIP_PARSE_URI added to parse an URI and return
a specified part of the URI.
Core
------------------
* ast_bt_get_symbols() now returns a vector of strings instead of an
array of strings. This must be freed with ast_bt_free_symbols.
res_pjsip
------------------
* New options 'trust_connected_line' and 'send_connected_line' have been
added to the endpoint. The option 'trust_connected_line' is to control
if connected line updates are accepted from this endpoint.
The option 'send_connected_line' is to control if connected line updates
can be sent to this endpoint.
The default value is 'yes' for both options.
res_rtp_asterisk
------------------
* The existing strictrtp option in rtp.conf has a new choice availabe, called
'seqno', which behaves the same way as setting strictrtp to 'yes', but will
ignore the time interval during learning so that bursts of packets can still
trigger learning our source.
------------------------------------------------------------------------------
--- Functionality changes from Asterisk 15 to Asterisk 16 --------------------
------------------------------------------------------------------------------
app_fax
------------------
* The app_fax module is now deprecated, users should migrate to the
replacement module res_fax.
app_originate
------------------
* An 'a' option has been added to the Originate dialplan application which
will execute the originate in an asynchronous fashion. If set then the
application will return immediately without waiting for the originated
channel to answer.
Build System
------------------
* MALLOC_DEBUG no longer has an effect on Asterisk's ABI. Asterisk built
with MALLOC_DEBUG can now successfully load binary modules built without
MALLOC_DEBUG and vice versa. Third-party pre-compiled modules no longer
need to have a special build with it enabled.
* Asterisk now depends on libjansson >= 2.11. If this version is not
available on your distro you can use `./configure --with-jansson-bundled`.
app_macro
------------------
* The app_macro module is now deprecated and by default it is no longer
built. Users should migrate to app_stack (Gosub). A warning is logged
the first time any Macro is used.
app_setcallerid
------------------
* The app_setcallerid module has been removed. The CALLERID dialplan function
should be used instead.
chan_sip
------------------
* New function SIP_HEADERS() enumerates all headers in the incoming INVITE.
* The variable GET_TRANSFERRER_DATA set in the peer channel causes matching
headers be retrieved from the REFER message and made accessible to the
dialplan in the hash TRANSFER_DATA.
chan_dahdi
------------------
* Timeouts for reading digits from analog phones are now configurable in
chan_dahdi.conf: firstdigit_timeout, interdigit_timeout, matchdigit_timeout.
AMI
------------------
* The ContactStatus and Status fields for the manager events ContactStatus
and ContactStatusDetail are now set to "NonQualified" when a contact exists
but has not been qualified.
* The "Newexten" event is now part of the "dialplan" class. The documentation
for Asterisk 15 already specified this, but the implementation was actually
using the "call" class instead.
ARI
------------------
* The ContactInfo event's contact_status field is now set to "NonQualified"
when a contact exists but has not been qualified.
app_queue
------------------
* Added the ability to set the wrapuptime in the configuration of member.
When set the wrapuptime on the member is used instead of the wrapuptime
defined for the queue itself.
* Added predial handler support for caller and callee channels with the
B and b options respectively. This is similar to the predial support
in app_dial.
res_config_sqlite
------------------
* The res_config_sqlite module is now deprecated, users should migrate to the
replacement module res_config_sqlite3.
res_monitor
------------------
* The res_monitor module is now deprecated, users should migrate to the
replacement module app_mixmonitor.
res_pjsip
------------------
* A new AMI action, PJSIPShowAors, has been added which displays information
about all configured PJSIP AORs.
* A new AMI action, PJSIPShowAuths, has been added which displays information
about all configured PJSIP Auths.
* A new AMI action, PJSIPShowContacts, has been added which displays information
about all configured PJSIP Contacts.
res_pjsip_registrar_expire
------------------
* The res_pjsip_registrar_expire module has been removed. The functionality has
been moved into res_pjsip_registrar.
func_audiohookinherit
------------------
* The func_audiohookinherit module has been removed. Due to architectural changes
in Asterisk 12, audiohook inheritance is performed automatically and this
function now lacks function.
cdr_syslog
------------------
* The cdr_syslog module is now deprecated and by default it is no longer
built.
cdr_sqlite
------------------
* The cdr_sqlite module has been removed. Users should move to using the
cdr_sqlite3_custom module instead.
format_jpeg
------------------
* The format_jpeg module has been removed.
pbx_dundi
------------------
* DUNDi now supports IPv6
Core:
------------------
* libedit is no longer available as an embedded library and must be provided
by the system.
* The STATIC_BUILD functionality has been removed as it has not been maintained
and has not worked in quite some time.
* The module loader now enforces inter-module dependencies. This ensures that
a module is not started before another it depends on, even if preload is used.
If a dependency is not available or fails to startup this will block any
dependants from startup.
* Parts of the Asterisk core which can load configuration from realtime are now
built-in modules. It is no longer necessary to preload realtime drivers as
they are always initialized before the built-in modules.
------------------------------------------------------------------------------
--- Functionality changes from Asterisk 15.5.0 to Asterisk 15.6.0 ------------
------------------------------------------------------------------------------
res_pjsip
------------------
* A new option 'suppress_q850_reason_headers' has been added to the endpoint
object. Some devices can't accept multiple Reason headers and get confused
when both 'SIP' and 'Q.850' Reason headers are received. This option allows
the 'Q.850' Reason header to be suppressed. The default value is 'no'.
res_pjsip_endpoint_identifier_ip
------------------
* Added regex support to the identify section match_header option. You
specify a regex instead of an explicit string by surrounding the header
value with slashes:
match_header = SIPHeader: /regex/
------------------------------------------------------------------------------
--- Functionality changes from Asterisk 15.4.0 to Asterisk 15.5.0 ------------
------------------------------------------------------------------------------
Core
------------------
* Core bridging and, more specifically, bridge_softmix have been enhanced to
relay received frames of type TEXT or TEXT_DATA to all participants in a
softmix bridge. res_pjsip_messaging and chan_pjsip have been enhanced to
take advantage of this so when res_pjsip_messaging receives an in-dialog
MESSAGE message from a user in a conference call, it's relayed to all
other participants in the call.
app_sendtext
------------------
* Support Enhanced Messaging. SendText now accepts new channel variables
that can be used to override the To and From display names and set the
Content-Type of a message. Since you can now set Content-Type, other
text/* content types are now valid.
app_confbridge
------------------
* ConfbridgeList now shows talking status. This utilizes the same voice
detection as the ConfbridgeTalking event, so bridges must be configured
with "talk_detection_events=yes" for this flag to have meaning.
* ConfBridge can now send events to participants via in-dialog MESSAGEs.
All current Confbridge events are supported, such as ConfbridgeJoin,
ConfbridgeLeave, etc. In addition to those events, a new event
ConfbridgeWelcome has been added that will send a list of all
current participants to a new participant.
res_pjsip
------------------
* Two new options have been added to the system and endpoint objects to
control whether, on outbound calls, Asterisk will accept updated SDP answers
during the initial INVITE transaction when 100rel is not in effect.
This usually happens when the INVITE is forked to multiple UASs and more
than one sends an SDP answer or when a single UAS needs to change a media
port to switch from custom ringback to the actual media destination.
The 'follow_early_media_forked' option sets whether Asterisk will accept
the updated SDP when the To tag on the subsequent response is different than
that on the the previous response. This usually occurs in the forked INVITE
scenario. The default value is "yes" which is the current behavior.
The 'accept_multiple_sdp_answers' flag sets whether Asterisk will accept the
updated SDP when the To tag on the subsequent response is the same as that
on the previous response. This can occur when a UAS needs to switch media
ports from custom ringback to the final media path. The default value is
"no" which is the current behavior.
These options have to be enabled system-wide in the system config section
of pjsip.conf as well as on individual endpoints that require the
functionality.
------------------------------------------------------------------------------
--- Functionality changes from Asterisk 15.3.0 to Asterisk 15.4.0 ------------
------------------------------------------------------------------------------
Core
------------------
* A new configuration option "genericplc_on_equal_codecs" was added to the
"plc" section of codecs.conf to allow generic packet loss concealment even
if no transcoding was originally needed. Transcoding via SLIN is forced
in this case.
res_pjproject
------------------
* Added the "cache_pools" option to pjproject.conf. Disabling the option
helps track down pool content mismanagement when using valgrind or
MALLOC_DEBUG. The cache gets in the way of determining if the pool contents
are used after free and who freed it.
res_pjsip_notify
------------------
* Extend the PJSIPNotify AMI command to send an in-dialog notify on a
channel.
------------------------------------------------------------------------------
--- Functionality changes from Asterisk 15.2.0 to Asterisk 15.3.0 ------------
------------------------------------------------------------------------------
Core
------------------
* During dialplan reload log messages are produced for each context,
extension and include. These messages are no longer printed by the
verbose loggers, they are now only logged as debug messages.
app_confbridge
------------------
* Added the Muted header to the ConfbridgeJoin AMI event to indicate the
participant's starting mute status.
* Made the AMI ConfbridgeList action's ConfbridgeList events output all
the standard channel snapshot headers instead of a few hand-coded channel
snapshot headers. The benefit is that the CallerIDName gets disruptive
characters like CR, LF, Tab, and a few others escaped. However, an empty
CallerIDName is now output as "<unknown>" instead of "<no name>".
app_followme
------------------
* Added a new prompt, connecting-prompt, which will be played
(if configured) to the "winner" callee before connecting the call.
res_pjsip
------------------
* Users who are matching endpoints by SIP header need to reevaluate their
global "endpoint_identifier_order" option in light of the "ip" endpoint
identifier method split into the "ip" and "header" endpoint identifier
methods.
* The pjsip_transport_event feature introduced in 15.1.0 has been refactored.
Any external modules that may have used that feature (highly unlikey) will
need to be changed as the API has been altered slightly.
res_pjsip_endpoint_identifier_ip
------------------
* The endpoint identifier "ip" method previously recognized endpoints either
by IP address or a matching SIP header. The "ip" endpoint identifier method
is now split into the "ip" and "header" endpoint identifier methods. The
"ip" endpoint identifier method only matches by IP address and the "header"
endpoint identifier method only matches by SIP header. The split allows the
user to control the relative priority of the IP address and the SIP header
identification methods in the global "endpoint_identifier_order" option.
e.g., If you have two type=identify sections where one matches by IP address
for endpoint alice and the other matches by SIP header for endpoint bob then
you can now predict which endpoint is matched when a request comes in that
matches both.
res_pjsip_pubsub
------------------
* In an earlier release, inbound registrations on a reliable transport
were pruned on Asterisk restart since the TCP connection would have
been torn down and become unusable when Asterisk stopped. This same
process is now also applied to inbound subscriptions. Since this
required the addition of a new column to the ps_subscription_persistence
realtime table, users who store their subscriptions in a database will
need to run the "alembic upgrade head" process to add the column to
the schema.
res_pjsip_transport_management
------------------
* Since res_pjsip_transport_management provides several attack
mitigation features, its functionality moved to res_pjsip and
this module has been removed. This way the features will always
be available if res_pjsip is loaded.
------------------------------------------------------------------------------
--- Functionality changes from Asterisk 15.1.0 to Asterisk 15.2.0 ------------
------------------------------------------------------------------------------
Core
------------------
* Added the "cache_media_frames" option to asterisk.conf. Disabling the option
helps track down media frame mismanagement when using valgrind or
MALLOC_DEBUG. The cache gets in the way of determining if the frame is
used after free and who freed it. NOTE: This option has no effect when
Asterisk is compiled with the LOW_MEMORY compile time option enabled because
the cache code does not exist.
chan_sip
------------------
* Calls to invalid extensions are now reported as an ACL failure security event
"no_extension_match".
res_rtp_asterisk
------------------
* The X.509 certificate used for DTLS negotation can now be automatically
generated. This is supported by res_pjsip by specifying
"dtls_auto_generate_cert = yes" on a PJSIP endpoint. For chan_sip, you
would set "dtlsautogeneratecert = yes" either in the [general] section of
sip.conf or on a specific peer.
res_pjsip
------------------
* The "identify_by" on endpoints can now be set to "ip" to restrict an endpoint
being matched based only on IP address. To ensure no behavior change the
default has been changed to "username,ip".
------------------------------------------------------------------------------
--- Functionality changes from Asterisk 15.0.0 to Asterisk 15.1.0 ------------
------------------------------------------------------------------------------
res_pjsip
------------------
* The "remove_existing" option now allows a registration to succeed by
displacing any existing contacts that now exceed the "max_contacts" count.
Any removed contacts are the next to expire. The behaviour change is
beneficial when "rewrite_contact" is enabled and "max_contacts" is greater
than one. The removed contact is likely the old contact created by
"rewrite_contact" that the device is refreshing.
AMI
------------------
* Added a new CancelAtxfer action that cancels an attended transfer.
------------------------------------------------------------------------------
--- Functionality changes from Asterisk 14 to Asterisk 15 --------------------
------------------------------------------------------------------------------
app_queue
------------------
* PAUSEALL/UNPAUSEALL now sets the pause reason in the queue_log if it has
been defined.
* A new option, "announce-position-only-up," has been added that, when set to
yes, causes position announcements to only be played when the caller's
queue position has improved since the last time that we annouced their
position. This default is no.
Build System
------------------
* '--with-pjproject-bundled' is now the default when running ./configure
It can be disabled with '--without-pjproject-bundled'.
* A '--with-download-cache' option is now available which is equivalent to
setting '--with-sounds-cache' and '--with-externals-cache' to the same
value. The download cache can also be set via the AST_DOWNLOAD_CACHE
environment variable.
------------------------------------------------------------------------------
--- Functionality changes from Asterisk 14.6.0 to Asterisk 14.7.0 ------------
------------------------------------------------------------------------------
res_pjsip
------------------
* The "external_media_address" on transports is now resolved using dnsmgr and
when dnsmgr refreshes are enabled will be automatically updated with the new
IP address of a given hostname.
* A new endpoint parameter "incoming_mwi_mailbox" allows Asterisk to receive
unsolicited MWI NOTIFY requests and make them available to other modules via
the stasis message bus.
res_musiconhold
------------------
* By default, when res_musiconhold reloads or unloads, it sends a HUP signal
to custom applications (and all descendants), waits 100ms, then sends a
TERM signal, waits 100ms, then finally sends a KILL signal. An application
which is interacting with an external device and/or spawns children of its
own may not be able to exit cleanly in the default times, expecially if sent
a KILL signal, or if it's children are getting signals directly from
res_musiconhoild. To allow extra time, the 'kill_escalation_delay'
class option can be used to set the number of milliseconds res_musiconhold
waits before escalating kill signals, with the default being the current
100ms. To control to whom the signals are sent, the "kill_method"
class option can be set to "process_group" (the default, existing behavior),
which sends signals to the application and its descendants directly, or
"process" which sends signals only to the application itself.
* New dialplan function PJSIP_DTMF_MODE added to get or change the DTMF mode
of a channel on a per-call basis.
res_xmpp
-----------------
* OAuth 2.0 authentication is now supported when contacting Google. Follow the
instructions in xmpp.conf.sample to retrieve and configure the necessary
tokens.
------------------------------------------------------------------------------
--- Functionality changes from Asterisk 14.5.0 to Asterisk 14.6.0 ------------
------------------------------------------------------------------------------
app_voicemail
------------------
* A new global option "imap_poll_logout" was added to specify whether need to
disconnect from the IMAP server after polling of mailboxes.
Default: no
res_pjsip
------------------
* A new endpoint option "refer_blind_progress" was added to turn off notifying
the progress details on Blind Transfer. If this option is not set then
the chan_pjsip will send NOTIFY "200 OK" immediately after "202 Accepted".
On default is enabled.
Some SIP phones like Mitel/Aastra or Snom keep the line busy until
receive "200 OK".
* A new endpoint option "notify_early_inuse_ringing" was added to control
whether to notify dialog-info state 'early' or 'confirmed' on Ringing
when already INUSE.
* The endpoint option 'dtmf_mode' has a new option 'auto_dtmf' added. This
mode works similar to 'auto' except uses DTMF INFO as fallback instead of
INBAND.
res_agi
------------------
* The EAGI() application will now look for a dialplan variable named
EAGI_AUDIO_FORMAT and use that format with the 'enhanced' audio pipe that
EAGI provides. If not specified, it will continue to use the default signed
linear (slin).
chan_pjsip
------------------
* When dialing an endpoint directly or using the PJSIP_DIAL_CONTACTS dialplan
function any contact which is considered unreachable due to qualify being
enabled will no longer be called.
* The asymmetric_rtp_codec option now also controls whether chan_pjsip will
send media as-is without transcoding if the codec has been negotiated in the
SDP. If set to "no" then Asterisk will only ever send the preferred codec
from the SDP, unless the remote side sends a different codec and we will
switch to match.
Build System
------------------
* Added a new PJPROJECT_CONFIGURE_OPTS environment variable which can be used
to pass arbitrary options to the bundled pjproject configure.
* Automatically set the bundled pjproject configure --host and --build
options to match those supplied for the asterisk configure.
------------------------------------------------------------------------------
--- Functionality changes from Asterisk 14.4.0 to Asterisk 14.5.0 ------------
------------------------------------------------------------------------------
res_rtp_asterisk
------------------
* Added the stun_blacklist option to rtp.conf. Some multihomed servers have
IP interfaces that cannot reach the STUN server specified by stunaddr.
Blacklist those interface subnets from trying to send a STUN packet to find
the external IP address. Attempting to send the STUN packet needlessly
delays processing incoming and outgoing SIP INVITEs because we will wait
for a response that can never come until we give up on the response.
Multiple subnets may be listed.
Logging
-------------------
* Added logger_queue_limit to the configuration options.
All log messages go to a queue serviced by a single thread
which does all the IO. This setting controls how big that
queue can get (and therefore how much memory is allocated)
before new messages are discarded.
The default is 1000.
res_pjsip_config_wizard
------------------
* Two new parameters have been added to the pjsip config wizard.
Setting 'sends_line_with_registrations' to true will cause the wizard
to skip the creation of an identify object to match incoming requests
to the endpoint and instead add the line and endpoint parameters to
the outbound registration object.
Setting 'outbound_proxy' is a shortcut for adding individual
endpoint/outbound_proxy, aor/outbound_proxy and registration/outbound_proxy
parameters.
res_hep_rtcp
------------------
* If the 'call-id' value is specified for the uuid_type option and a
chan_sip channel is used the resulting HEP traffic will now contain the
SIP Call-ID instead of the Asterisk channel name.
------------------------------------------------------------------------------
--- Functionality changes from Asterisk 14.3.0 to Asterisk 14.4.0 ------------
------------------------------------------------------------------------------
Build System
------------------
* LOW_MEMORY no longer has an effect on Asterisk ABI. Symbols that were
previously suppressed by LOW_MEMORY are now replaced by stub functions.
Asterisk built with LOW_MEMORY can now successfully load binary modules
built without LOW_MEMORY and vice versa.
* RADIUS backends for CEL and CDR can now also be built using the radcli
client library, in addition to the existing support for building them
using either freeradius or radiusclient-ng.
Core
------------------
* ASTERISK_REGISTER_FILE was no longer useful and has been removed. Sources
which use mtx_prof must now manually declare and initialize the variable.
chan_sip
------------------
* If an offer is received with optional SRTP (a media stream with RTP/AVP but
which contains a crypto line) chan_sip will now accept it and enable SRTP.
If you would like to do optional SRTP on outbound you will need to create
a dialplan that dials with it enabled initially and if it fails fall back to
without.
res_pjsip
------------------
* Added endpoint configuration parameter "preferred_codec_only".
This allow asterisk response to a SIP invite with the single most
preferred codec rather than advertising all joint codec capabilities.
This limits the other side's codec choice to exactly what we prefer.
cdr_radius
------------------
* To fix a memory leak the syslog channel is now empty if it has not been set
and used by a syslog channel in the logger.
cel_radius
------------------
* To fix a memory leak the syslog channel is now empty if it has not been set
and used by a syslog channel in the logger.
RTP
------------------
* New setting "rtp_pt_dynamic = 35" in asterisk.conf:
Normally the Dynamic RTP Payload Type numbers are 96-127, which allow just 32
formats. To avoid the message "No Dynamic RTP mapping available", the range
was changed to 35-63,96-127. This is allowed by RFC 3551 section 3. However,
when you use more than 32 formats and calls are not accepted by a remote
implementation, please report this and go back to rtp_pt_dynamic = 96.
* A new setting, "rtp_use_dynamic", has been added in asterisk.conf". When set
to "yes" RTP dynamic payload types are assigned dynamically per RTP instance.
When set to "no" RTP dynamic payload types are globally initialized to pre-
designated numbers and function similar to static payload types.
app_originate
------------------
* Added support to gosub predial routines on both original channel and on the
created channel using options parameter (like app_dial) B() and b(). This
allows for adding variables to newly created channel or, e.g. setting callerid.
CLI Commands
------------------
* 'dialplan show' output will now show [config_file:line_number] instead of
[registrar] when that information is available. Currently only extensions
registered by pbx_config when loading/reloading will use this format.
app_queue
------------------
* Add 'QueueUpdate' application which can be used to track outbound calls
using app_queue.
pbx_spool
------------------
* Asterisk will now set the AST_OUTGOING_ATTEMPT channel variable so that
attempt-specific behavior is possible. This is a 1-based number that
simply increases by 1 for each attempt.
------------------------------------------------------------------------------
--- Functionality changes from Asterisk 14.3.0 to Asterisk 14.4.0 ------------
------------------------------------------------------------------------------
AMI
------------------
* The 'PJSIPShowEndpoint' command's respone event of 'IdentifyDetail' now
contains a new optional parameter, 'MatchHeader', mapping to the new
configuration option 'match_header' for the corresponding 'identify' object.
It should be noted that since 'match_header' takes in a key: value pair, the
event parameter will contain a ':' as well.
app_record
------------------
* Added new 'u' option to Record() application which prevents Asterisk from
truncating silence from the end of recorded files.
res_pjsip_outbound_registration
------------------
* Outbound registrations are now refreshed when res_stun_monitor detects
a network change event has happened.
The 'pjsip send (un)register' CLI commands were updated to accept '*all'
as an argument to operate on all registrations.
The 'PJSIP(Un)Register' AMI commands were updated to also accept '*all'.
app_voicemail
------------------
* The 'Comedian Mail' prompts can now be overriden using the 'vm-login' and
'vm-newuser' configuration options in voicemail.conf.
* Added 'fromstring' field to the voicemail boxes. If set, it will override
the global 'fromstring' field on a per-mailbox basis.
func_channel
------------------
* Added CHANNEL(callid) to retrieve the call log tag associated with the
channel. e.g., [C-00000000] Dialplan now has access to the call log
search key associated with the channel so it can be saved in case there
is a problem with the call.
res_pjsip
------------------
* A new transport parameter 'symmetric_transport' has been added.
When a request from a dynamic contact comes in on a transport with this
option set to 'yes', the transport name will be saved and used for
subsequent outgoing requests like OPTIONS, NOTIFY and INVITE. It's
saved as a contact uri parameter named 'x-ast-txp' and will display with
the contact uri in CLI, AMI, and ARI output. On the outgoing request,
if a transport wasn't explicitly set on the endpoint AND the request URI
is not a hostname, the saved transport will be used and the 'x-ast-txp'
parameter stripped from the outgoing packet. To facilitate recreation of
subscriptions on asterisk restart, a new column 'contact_uri' needed to be
added to the ps_subcsription_persistence table. Since new columns were
added to both transport and subscription_persistence, an alembic upgrade
should be run to bring the database tables up to date.
* A new option, allow_overlap, has been added to endpoints which allows
overlap dialing functionality to be enabled or disabled. The option defaults
to enabled.
res_pjsip_transport_websocket
------------------
* Removed non-secure websocket support. Firefox and Chrome have not allowed
non-secure websockets for quite some time so this shouldn't be an issue
for people. Attempting to use a non-secure websocket may or may not work
when Asterisk attempts to send SIP requests to do something like initiate
call hangup.
res_pjsip_endpoint_identifier_ip
------------------
* A new option has been added to the 'identify' configuration object,
'match_header'. The 'match_header' attribute should contain a SIP
header: value pair that, When set, will cause inbound requests that contain
the matching SIP header/value pair to be associated with the corresponding
endpoint. This option is cumulative with the 'match' option, so that if
either option matches the request, the request is associated with the
endpoint.
In a future release, this module will be renamed to something more
appropriate, as it now matches inbound requests on more than just IP
address.
res_rtp_asterisk
-----------------
* The RTP layer of Asterisk now has support for RFC 5761: "Multiplexing RTP
Data and Control Packets on a Single Port." So far, the only channel driver
that supports this feature is chan_pjsip. You can set "rtcp_mux = yes" on
a PJSIP endpoint in pjsip.conf to enable the feature.
------------------------------------------------------------------------------
--- Functionality changes from Asterisk 14.2.0 to Asterisk 14.3.0 ------------
------------------------------------------------------------------------------
res_pjproject
------------------
* Added new CLI command "pjproject set log level". The new command allows
the maximum PJPROJECT log levels to be adjusted dynamically and
independently from the set debug logging level like many other similar
module debug logging commands.
* Added new companion CLI command "pjproject show log level" to allow the
user to see the current maximum pjproject logging level.
* Added new pjproject.conf startup section "log_level' option to set the
initial maximum PJPROJECT logging level.
res_pjsip_outbound_registration
------------------
* Statsd no longer logs redundant status PJSIP.registrations.state changes
for internal state transitions that don't change the reported public status
state.
res_pjsip_registrar
------------------
* The PJSIPShowRegistrationInboundContactStatuses AMI command has been added
to return ContactStatusDetail events as opposed to
PJSIPShowRegistrationsInbound which just a dumps every defined AOR.
res_pjsip
------------------
* Six existing contact fields have been added to the end of the
ContactStatusDetail AMI event:
ID, AuthenticateQualify, OutboundProxy, Path, QualifyFrequency and
QualifyTimeout. Existing fields have not been disturbed.
res_pjsip_endpoint_identifier_ip
------------------
* SRV lookups can now be done on provided hostnames to determine additional
source IP addresses for requests. This is configurable using the
"srv_lookups" option on the identify and defaults to "yes".
ARI
------------------
* The 'ari set debug' command has been enhanced to accept 'all' as an
application name. This allows dumping of all apps even if an app
hasn't registered yet.
* 'ari set debug' now displays requests and responses as well as events.
------------------------------------------------------------------------------
--- Functionality changes from Asterisk 14.1.0 to Asterisk 14.2.0 ------------
------------------------------------------------------------------------------
AMI
------------------
* Events that reference a bridge may now contain two new optional fields:
- 'BridgeVideoSourceMode': the video source mode for the bridge.
Can be one of 'none', 'talker', or 'single'.
- 'BridgeVideoSource': the unique ID of the channel that is the video
source in this bridge, if one exists.
* A new event, BridgeVideoSourceUpdate, has been added with a class
authorization of CALL. The event is raised when the video source changes
in a multi-party mixing bridge.
ARI
------------------
* The bridges resource now exposes two new operations:
- POST /bridges/{bridgeId}/videoSource/{channelId}: Set a video source in a
multi-party mixing bridge
- DELETE /bridges/{bridgeId}/videoSource: Remove the set video source,
reverting to talk detection for the video source
* The bridge model in any returned response or event now contains the following
optional fields:
- video_mode: the video source mode for the bridge. Can be one of 'none',
'talker', or 'single'.
- video_source_id: the unique ID of the channel that is the video source
in this bridge, if one exists.
* A new event, BridgeVideoSourceChanged, has been added for bridges.
Applications subscribed to a bridge will receive this event when the source
of video changes in a mixing bridge.
* The ARI major version has been bumped. There are not any known breaking changes
in ARI. The major version has been bumped because otherwise we can end up with
overlapping version numbers between different Asterisk versions. Now each major
version of Asterisk will bring with it a change in the major version of ARI.
The ARI version in Asterisk 14 is now 2.0.0.
res_pjsip
------------------
* Automatic dual stack support is now implemented. Depending on DNS resolution
and the transport used for sending a message the SIP signaling and SDP will
be updated with the correct IP address and protocol version. This means that
the rtp_ipv6 and t38_udptl_ipv6 options no longer have any effect. The
res_pjsip_multihomed module has also been moved into core res_pjsip to ensure
that messages are updated with the correct address information in all cases.
chan_pjsip
------------------
* The default behavior for RTP codecs has been changed. The sending codec will
now match the receiving codec. This can be turned off and behavior reverted
to asymmetric using the "asymmetric_rtp_codec" endpoint option. If this
option is set then the sending and received codec are allowed to differ.
CLI Commands
------------------
* Three new CLI commands have been added for ARI:
- ari show apps:
Displays a listing of all registered ARI applications.
- ari show app <name>:
Display detailed information about a registered ARI application.
- ari set debug <name> <on|off>:
Enable/disable debugging of an ARI application. When debugged, verbose
information will be sent to the Asterisk CLI.
Queue
------------------
* A new dialplan variable, ABANDONED, is set when the call is not answered
by an agent.
res_ari
------------------
* The configuration file ari.conf now supports a channelvars option, which
specifies a list of channel variables to include in each channel-oriented
ARI event.
------------------------------------------------------------------------------
--- Functionality changes from Asterisk 14.0.0 to Asterisk 14.1.0 ------------
------------------------------------------------------------------------------
Build System
------------------
* The res_digium_phone, codec_g729a, codec_silk, codec_siren7 and
codec_siren14 binary modules hosted at downloads.digium.com can now be
automatically downloaded and installed during the Asterisk install
process. If selected in menuselect, when 'make install' is run, the
script will check the downloads site for a new version and download
and install it if needed. The '--with-externals-cache' option to
./configure can be used to specify a location to cache the latest
tarballs so they don't have to be re-downloaded for every install.
app_voicemail
------------------
* Added "tps_queue_high" and "tps_queue_low" options.
The options can modify the taskprocessor alert levels for this module.
Additional information can be found in the sample configuration file at
config/samples/voicemail.conf.sample.
res_pjsip_mwi
------------------
* Added "mwi_tps_queue_high" and "mwi_tps_queue_low" global configuration
options to tune taskprocessor alert levels.
* Added "mwi_disable_initial_unsolicited" global configuration option
to disable sending unsolicited MWI to all endpoints on startup.
