=====
ABC starts your Conference Bridge(s) in ASTERISK(R) by sending calls to up
to forty-two other participants, making it easier for both you and your Friends
to stay connected using audio and (starting in version 16i) even some video.
ABC requires ASTERISK version 16 or greater to already be installed and working.
ABC can be integrated into existing FreePBX(R) setups -- see mini-HOWTO below.
ABC is almost entirely contained in the single file you are reading right now.
This file is written in ASTERISK Extension Language dial plan format. Ideally,
you will only need to include this file as new dial plan configuration, then
jump to it from your existing "extensions.conf" or "extensions_custom.conf"
files. See Examples 1-10 below for some integration ideas. Other config files
to look at include "confbridge.conf", "indications.conf" and "voicemail.conf".
Also you can create an "abc.conf" file in the same directory for more control.
Generally you will only need minimal modifications to get working with ABC.
There are many use cases considered by ABC, improving with each release.
Earliest versions cared about fast conf calls; version 16c added emergency call
nice-things-to-have; single codec video was added in 16i; followed by Work From
Home/Phone scenarios in version 16k.
ABC IS YOUR FREE GIFT, AS-IS, WITH NO WARRANTY!!!
ABC Use Case: Emergency Outbound Calls (EOC)
--------------------------------------------
ABC can be configured to immediately notify your Friends, Trolls and/or Paladins
of your call attempts. The caller ID information they see on their SIP phones
will show them your name; your phone number; your GPS co-ordinates including
elevation, depth, room, floor, or building number (if configured); and the
Remote End destination phone number that you originally dialed (the DNID.)
When your Friends answer their phones, they will hear some short notes (A-B-C),
and (optionally) a Text-To-Speech (TTS) play back of your GPS co-ordinates, and
then be connected to talk with you and other Friends in your "Yurt" conference room.
In Simple Mode, Friends will even be able to talk with you *before the Remote End
answers* -- very helpful if the Remote End *never answers* due to technical/capacity
failures outside of your network!
Also in Simple Mode, the conference will continue until all parties disconnect
-- even if the OriGinal caller (you the O.G.) hang up the phone before anybody
else "really" answers and starts talking!
Instead of Friends, or in addition to them, if you use Paladins, they will be
placed into a separate conference -- the "Palace" -- all by themselves. They
won't be able to talk with you -- like your Friends in the "Yurt" conference
-- but Paladins will be able to hear you and Remote End talking, and Paladins
can talk to each other to help co-ordinate the local response to your call.
(Sometimes Paladins don't listen to the Yurt, instead they just enter the
Palace and talk amongst themselves -- but that is still triggered by the O.G.
and fully configurable from within ABC.)
Related, Trolls are in the Yurt with you the OG caller, the Remote End, and
any Friends; but Trolls can only listen and not speak to anyone. Also Trolls
only get two DTMF menu options (to change their listening volume up or down.)
Sometimes Trolls are not people but blinking lights or overhead speakers playing
back alert messages -- up to you.
ABC Use Case: Work From Home (WFH)
AKA Insta Teams Mode (ITM)
----------------------------------------
ABC can be configured in Insta Teams Mode, to help you reach out to your Team
without them having to remember all the conference call details themselves,
making it easier for you to start-up Yurts with your Friends. You might just
send an email that says "I'll give y'all a call tomorrow morning between 10
and 11." Then tomorrow you call your ABC phone number, authorize the call to
start spooling out to your Team, and then join in talking with everyone who
accepts the invitation to your Yurt.
There are several differences in this Use Case...
In contrast with emergency calls, in Teams Mode your Friends will *NOT* be
immediately placed into the Yurt -- they will hear a short message from you and
then a message asking them to join via "press 1" keypad option. This helps
prevent your Yurt from getting stuck in somebody's cell phone voicemail system.
Also, there are no Paladins or Trolls in this mode. And Friends in Teams Mode
won't hear your GPS co-ordinates (like they do in emergency modes). In-call
menu options are a little different, too.
You might think of the Work From Home / Insta Teams Mode solution as a sort of
mini-town hall teleconference, complete with features like *9 for raising your
hand.
abc.conf
========
This tiny file can go into your /etc/asterisk/ directory, but it is currently
only used in Insta Teams Mode, and even then it is not required:
[general]
[teams]
conferenceminutes=120 ; maximum length for one conference
monthlyminutes=600 ; allowed cumulative conference minutes for the month
vmcontext=default ; voicemail context used to authenticate users
numberstyle=us ; default is 'international' for robo number speech
TESTING
=======
ABC is tested most with PJSIP on ASTERISK certified version 16.3-cert1.
It should also work okay with other channel techs -- see DAHDI in Example #2.
And chan_sip should mostly work (see PJSIP_DIAL_CONTACTS and PJSIP_HEADERS for
exceptions.)
Extension 922 is used often in the ABC Examples -- see below -- although any
extension number 0-9A-Za-z should work. But you should test it yourself.
Really, you should test and verify everything in ABC that you intend to use!
If you are not comfortable with that, or even if you are, please consider talks
with your neighborhood free/libre/open source software folks for separate
support/warranty consulting services.
ABC IS YOUR FREE GIFT, AS-IS, WITH NO WARRANTY!!!
FEATURES
========
~ Multiple notifications.
~ Dynamic call back numbers.
~ Caller ID based on Subnet ID.
~ Update phone GPS with included IVR.
~ Encrypted local storage of GPS info.
~ Dynamic Location Routing per RFC 6442.
~ Text-To-Speech of GPS and additional information.
~ Record each leg of the call in separate WAV files.
~ Automatically bridge in callees (Simple Mode.)
~ Wait for answer before bridging (Tin Can Mode.)
~ Prompt for key to confirm answer (Insta Teams Mode.)
~ Easy integration with existing ASTERISK and FreePBX installations.
KNOWN BUGS
==========
~ Callers from the same extension number dialing the same destination
number will end up in the same call path. This could happen when users
dial 922 from their laptop soft phone at the same time as dialing 922
from their desktop phone. The recommended workaround is to use separate
extension numbers for each device registration.
~ DTMF pass through is not activated. Kind of a bug/feature.
TODO LIST
=========
Most TODO items are sprinkled throughout the configuration where neededed.
Here's the more general items for EOC scenario:
~ Support telecommunications relay services via MESSAGE functions.
~ Pidgin example using SIMPLE driver to see pop-up notifications on PCs.
~ SMS support for Text-to-Remote end.
~ Friends option to start out muted - on a friend by friend basis,
then press 1 to un-mute at any time.
~ Multicast addresses for paging.
~ Add option 8 for "U"sers - to list out the roll of users in the conf.
~ Finish CLIPS codes for appending to Emergency Caller ID number and/or
dialed number - either way it is for parsing by the telco, to map the codes

===============================================================
Only 95 lines! But up and running in 5 minutes!
This demo assumes all phones are using same channel technology.
This could be all chan_PJSIP, or all chan_SIP, or all chan_DAHDI,
or all chan_IAX, or others - depending on your configuration.
For new installs, chan_PJSIP is recommended.
1. First, SSH into your PBX, and then run the following commands:
#BEGIN_MINI_COMMANDS#
# MaKe DIRectory
mkdir ~/abc
# Change Directory
cd ~/abc
# download this file into the new "abc" directory
# TODO: nobody user in /tmp
wget https://raw.githubusercontent.com/chrsmj/always-be-conferencing/master/extensions-pngnpbx-abc-v16k.ael2
# ECHO line into dial plan - AEL format used by ABC
echo '#include "extensions-pngnpbx-abc-v16k.ael2"' > extensions.ael
# ECHO line into dial plan - CONF format used by FreePBX
echo '[from-internal-custom]' > extensions_custom.conf
# add some glued lines to the CONF dial plan file
echo 'exten => _123*222,1,Goto(pngnpbx-abc-demo,${EXTEN},1)' >> extensions_custom.conf
echo 'exten => _123*222*,1,Goto(pngnpbx-abc-demo,${EXTEN},1)' >> extensions_custom.conf
echo 'exten => _123*222*.,1,Goto(pngnpbx-abc-demo,${EXTEN},1)' >> extensions_custom.conf
echo 'exten => _123*222X*.,1,Goto(pngnpbx-abc-demo,${EXTEN},1)' >> extensions_custom.conf
# Show DIFFerences with current FreePBX custom extensions.
diff -u extensions_custom.conf /etc/asterisk/extensions_custom.conf
# Check for any AEL dial plan, using same command.
diff -u extensions.ael /etc/asterisk/extensions.ael
# LiSt existing files, with four options.
ls -last /etc/asterisk/extensions_custom.conf
ls -last /etc/asterisk/extensions.ael
#END_MINI_COMMANDS#
2. If there's no existing files or no major differences, then copying
should be fairly straight forward, with help from "sudo" command:
#BEGIN_MINI_SUDO_COMMANDS#
# CoPy with "-i" option to prompt before overwrite.
sudo cp -i ~/abc/extensions* /etc/asterisk/
# Non-sudo check of file details.
ls -last /etc/asterisk/extensions_custom.conf
ls -last /etc/asterisk/extensions.ael
#END_MINI_SUDO_COMMANDS#
If there are any errors on the copying, then you should manually inspect
the files for conflicts. Most likely, the only conflict will be with the
extensions_custom.conf files. Check those carefully before any mergers.
If extensions_custom.conf already exists, then you will need to insert the
ABC "_123*222..." config lines into the existing [from-internal-custom]
context (or create the context if it does not already exist.)
3. After completing the file copying, exit SSH and open up your PBX GUI.
Issue a full PBX reload using your GUI (sometimes you have to make a small
change to get the "Apply Config" button to appear, so make a trivial thing
like adding ABC after your name, then "Submit", then "Apply Config".)
4. The "Apply Config" process may take a minute.
5. Finally, start making test calls from your desk phone, with big dial strings:
123*2223*1000*2000*3000
...replacing 1000 with an extension acting as your "Remote End" operator
and replacing 2000 and 3000 with your own local "friend" extensions.
(You can shorten these in the future - remember this is the demo :)
To hear your GPS co-ordinates, any participant can press * at any time
during the call. To stop the bot playback, any participant can press #.
See additional conference bridge menu options below - there are also
different options available, based on the nature of the call.
To silence the ring-back you hear from friend's phones, but not the
Remote End, you can run the following command on the ASTERISK CLI:
sirius*CLI> indication add us silent 0/15000
Thus ends the mini-HOWTO. HTH!
PREREQUISITE: The ASTERISK Extension Language (AEL)
===================================================
This is not your standard dial plan "/etc/asterisk/extensions.conf" file!
ABC is configured in the ASTERISK Extension Language (AEL). AEL syntax is
converted into standard CONF file format when loaded in to system memory
by ASTERISK. But you should not need to edit this ABC AEL file very often,
if ever. It only needs to be *included* into your dialplan.
Please copy this file into your "/etc/asterisk/" directory and set it to
read-only permission for the user/group your ASTERISK process runs as (usually
"root" or "asterisk".)
To confirm you have AEL working in your install of ASTERISK, you can run this
command on the ASTERISK CLI:
sirius*CLI> core show help ael
...which, if loaded properly, should list "ael reload" and "ael set debug".
Otherwise, if this is your first time using AEL, then you may need to manually
load the module, or take other steps. This may include rebuilding from source
code eg. selecting the AEL module when using "make menuconfig".
After confirming AEL is active and working, edit (or create) this file:
/etc/asterisk/extensions.ael
And add this line (with no spaces at the front):
#include "extensions-pngnpbx-abc-v16k.ael2"
...then save the file. Now you should be able to load the AEL config and view
the in-memory dial plan in CONF format:
sirius*CLI> ael reload
sirius*CLI> dialplan show pngnpbx-abc-dial
If that works, and you see a bunch of dial plan looking output, Congratulations!
You are now able to use ABC from standard dial plan in "extensions.conf" file
-- or in the "extensions_custom.conf" file if you are using FreePBX.
Tin Can Mode
============
If you choose this mode, then ABC will use Dial() instead of Originate() at the
start of the call to the Remote End. This is to help satisfy requirements in
some situations where it is deemed desirable to only route the call and not
answer the caller via immediate bridging. Particularly this is for emergency
calling situations.
There are several potential shortcomings in Tin Can mode compared to Simple
Mode and Teams Mode, including the following caveats:
0. In Simple Mode, everyone can always talk to each other.
In Teams Mode, Friends do not enter the Yurt until they press 1 to opt-in.
In Tin Can Mode, caller cannot talk to Friends until Remote End answers.
But, Friends can talk to each other, hear your GPS with * key, etc.
1. In Simple Mode, everyone always gets access to DTMF menu options, because
they are always in the Yurt.
2. In Teams Mode, Friends must press 1 to join, then it is basically just
like Simple Mode.
3. In Tin Can Mode, Friends will not get access to DTMF menu options until the
Remote End answers. Then, everyone will get access, same as Simple Mode.
4. In Tin Can Mode, there may be a few more frames of feedback immediately
after the Remote End answers. (TODO: Fix this in a future release.)
5. In Tin Can Mode ONLY, when caller hangs up before Remote End answers, then
the call will drop. (TODO: Fix this in a future release.)
PRIVACY
=======
The handling of exact GPS co-ordinates of each phone presents multiple safety,
security, and privacy concerns. (See RFCs 3693, 6280, 6442 and 6772.)
ABC considers carefully each of the six basic Geopriv roles introduced in
RFC 3693 and later refined in RFC 6280 Section 3.2, to wit:
1. Target: ABC can be the Target, or Targets can be User-based or Device-based.
2. Device: ABC can be the Device, but more commonly it will be your SIP phone.
3. Rule Maker: ABC provides RM functions. (See Conference Bridge DTMF options.)
4. Location Generator: ABC can be the LG. (See DIY GPS IVR for users/admins.)
5. Location Server: ABC can perform LS. (See encrypted internal AstDB storage.)
6. Location Recipient: ABC considers almost all participants as potential LRs.
ABC tries to get the DL to the LRs by multiple automatic and manual methods.
With ABC as your LS, your personal location data is not *pre-registered* with
any 3rd-party remote/hosted/cloud/government/etc. services in large centralized
databases, with all of the associated privacy and data safety issues that can
entail. But new regulations, such as those covering finer detail refinements in
Dispatchable Location (DL) info, threaten to dramatically increase the size and
scope of these centralized LS databases, opening up previously unknown employee
where-abouts to 'manual ALI query' and other privacy attacks in the future.
In the author's opinion, too many SIP providers are complying with changing
regulatory requirements by (un)intentionally sacrificing liberty in exchange
for safety, acting as the LS when that is wholly un-necessary. While not
exactly *security theater*, the choice between exposing personal information
outside of your PBX/MLTS only at the time of an emergency vs. storing it all
of the time with the telephone company is not to be taken lightly if you value
the privacy of your users. (Do you even SSH or VPN bro ?)
ABC takes a more dynamic approach (Dynamic Location Routing) instead of the
old Registered Address system. ABC only releases your location details
from the local PBX system when it is needed. Until then, ABC can store your data
at rest in encrypted format on the local ASTERISK system's internal SQLite
database (AstDB) using a separate key file. This prevents bulk dumping of clear
text data via ASTERISK CLI commands like "database show".
By default, the key is located on the filesystem in the /var/lib/asterisk/keys/
directory. When you automate backup processes, then you may want to consider
changing these slightly, for example, to not include the AstDB in directory
/var/lib/asterisk/ with /var/lib/asterisk/keys/ directory in the same tarball.
(That would be like hiding the key under the door mat.)
Or, you might consider changing the location of the default key file used for
GPS data encryption (TODO: make this easier in a future ABC revision.)
However, should you lose the key file, then users will need to manually
re-update their GPS XYZ co-ordinates, using the included IVR as the LG. Until
they do, the PBX will not know where they are, and it will fail when trying to
do things like send those co-ordinates to the Remote End LR.
Steps to (re)create the key file:
sudo mkdir /var/lib/asterisk/keys
sudo touch /var/lib/asterisk/keys/pngnpbx-abc-key.txt
sudo chown asterisk.asterisk /var/lib/asterisk/keys/pngnpbx-abc-key.txt
Feel free to store 16 random alpha-numeric characters in that file,
otherwise, a somewhat random string will be used.
Of course, you are free to forego the novel location features, and stick with
the Registered Address system offered by your telephone company. ABC is still
totally compatible with those types of legacy solutions.
LOGGING
=======
Call Detail Records will be saved in files based on whatever ABC account name
you specify ie. the account code will be set to this name on (almost) all
channels. In the examples (below) it would be "abctest.csv" in the same
directory as your "Master.csv" (assuming you are using CSV for CDRs.)
Optionally you can record the call (see example #2 below).
Look for the recordings in "/var/spool/asterisk/monitor/" directory.
The ABC account name will be used to prefix the files (one file per leg.)
CAREFUL when recording eg. legal issues, drive space, privacy, etc.
EXAMPLES
========
YOU MUST CHANGE #YOUR-TRUNK-s#, the "ABCTO" number, the extension numbers, and
choose valid Call-Back numbers, whenever copy-pasta'ing these examples !!!
But please feel free to copy the next 365 lines directly into your dial plan,
appended somehow to your extensions.conf or extensions_custom.conf files.

; ------------------------------------
; * In Tin Can Mode (Again)
; * Integrates with FreePBX per-device emergency_cid numbers.
; * Creates separate conference for paladins to discuss amongst themselves.
; * Runs parallel to the existing call/conf from OG caller to Remote End.
; * Does not allow paladins to interfere in call from OG caller to Remote End.
; * Only feeds in audio to paladins when Remote End answers the OG caller.

; -------------------------------------------------------------------
; * In Tin Can Mode (Yes, Again)
; * Paladins only - nosy ones that cause the Palace to listen to the Yurt.
; * Choose caller ID based on subnet ID - requires new AstDB entries eg...

; * The smallest subnet found is used first (so /30 before /29, down to /24).
; * Defaults to FreePBX emergency CID if no subnet override CID is found.

Frequently Asked Questions (FAQs)
=================================
Question:
What are the conference menu options in EOC modes ?
Answer:
* SPLAT - YOU ARE HERE! TTS the GPS of the caller into the conference.
# Hash - "H"alts any TTS / automated message playbacks.
0 Operator (TODO: Play back all of the menu options. Just to your phone.)
1 Count out number of participants in the conference.
2 "A"dditional information (eg. Room Number) is spoken into the conference.
3 "D"ecrease listening volume - only on your phone.
4 "I"ncrease listening volume - only on your phone.
5 "L"ocal extension number is spoken into the conference.
6 "N"umber to call back and reach the caller is spoken into the conference.
7 "S"treet address and additional info of caller spoken into the conference.
8 TBD
9 "Y"es - Sends audio "yes dear" eg. when asked yes/no question by operator.
Question:
What are the conference menu options in Insta Teams Mode / Work From Home ?
Answer:
USERS
*2 increase listening volume - only on your phone.
*3 "D"ecrease listening volume - only on your phone.
*6 "M"ute or un"M"ute yourself
*9 "W"ave hand / make a point of order/information request
** Playback user menu options.
ADMIN
*2 increase listening volume - only on your phone.
*3 "D"ecrease listening volume - only on your phone.
*4 "H"angup the conference.
*5 "L"ock conference.
*6 "M"ute or un"M"ute yourself.
*7 TBD
*8 "T"ry dialing Friends again if they did not answer or hung up too early.
*9 "W"ave hand / make a point of order/information request.
99 Mute or unMute ALL participants.
*# Count out number of participants in the conference.
** Playback admin menu options.
Question:
Who is in the "yurt" vs. the "palace" conference rooms ?
Answer:
The "yurt" is for OG caller, Remote End, friends (if any) and trolls
(if any.)
The "palace" is for the paladins (if any.) Palaces can read audio from yurt
streams but not write back to them. Paladins can still access DTMF menu
options and talk to other paladins. They just can't talk to OG caller,
Remote End, nor any of the OG caller's friends. Nor will Trolls hear
Paladins.
Question:
Can I integrate ABC with FreePBX ?
Answer:
Yes, there are several examples which highlight this. But ABC needs to
take over the call flow very early on. It will probably not work from
something like a predial macro hook. Instead, use [from-internal-custom]
context inclusion methods; or Custom Destination & Misc Application; or
per-device context adjustment (may be under the Extension's Advanced tab.)
Question:
Why do I hear ring back tone until the friend(s) pick up and answer ?
Answer:
You'll need to add a new line to indications.conf for each tone zone
you offer to your users in order to produce a 'silent' ringer.
(...scroll down to find the section...)
[us]
description = United States / North America
silent = 0/15000
(...the rest of the tones...)
...but to avoid a restart, for testing, on the ASTERISK CLI, you can do:
sirius*CLI> indication add us silent 0/15000
Question:
Why use 922 as the example extension that users will dial to reach 933 ?
Answer:
It is currently only used for the police in Tonga. And it might help
users distinguish between competing providers of different brands of
operator services at the Remote End. Any 9XX number in the following
ranges should be good to test with in most countries:
901-910
914-918
920-932
934-976
978-989
Lots of regions use 1XX numbers. ABC is configurable. It is up to you.
Please consult your local numbering plan rules before making changes.
You might even decide to ABC-enable several different outbound numbers!
Question:
Wait, could ABC be used to help open up free market competition with
existing emergency operator service monopolies in given geographic areas,
without pre-loading private personal GPS address information for every
telecommuter in the USA up in to massive centralized databases of detailed
location directions to the nation's critical infrastructure ?
Answer:
Maybe but that is currently beyond the scope of this technical document.
