=====
ABC starts your Conference Bridge in ASTERISK(R) by Originating calls to up
to twenty other participants, after you dial just one (configurable) number.
Your friends' phones will immediately be notified of your call attempt.
The caller ID information they see on their SIP phones will show them your name,
number, GPS co-ordinates (if configured), and the remote end destination number
you originally dialed (the DNID).
When your friends answer the phone, they will hear some short notes (A-B-C),
and then be able to talk with you. In Simple Mode, they will even be able to
talk with you *before the remote end answers*!
Also in Simple Mode, the conference will continue until all parties disconnect
-- even if the original caller (you) hang up the phone before anybody else
"really" answers and starts talking!
ABC is tested most with PJSIP on ASTERISK certified version 16.3-cert1.
It should also work with any channel technology (see DAHDI in Example #2.)
Non-numeric extension numbers should work, but you should test it yourself.
Really, you should test and verify everything in ABC that you intend to use!
FEATURES
========
~ Instant (Simple Mode) or delayed (Tin Can Mode) bridging for caller.
~ Dynamic temporary pool call back number <-> caller ID mapping and routing.
~ DIY phone-based geolocation update support for changing GPS info via IVR.
~ Single press DTMF options to play back Dispatachable Location in-band.
~ Same DTMF options also display the DL info on the desk phone screen.
~ Optional automated playback of GPS co-ordinates to remote end upon answer.
~ Preliminary support for RFC6442 Geolocation headers with some SIP providers.
~ Saves first N seconds of call as voicemail (to email/pager) (if configured.)
~ Optional full call recording of each participant leg of the conference.
~ Easy integration with existing ASTERISK and FreePBX(R) installations.
~ Coming Soon: Complete Ansibilized build on fresh Debian 10.
Quick Start mini-HOWTO for first time ABC users on FreePBX
==========================================================
1. First, SSH into your PBX, and then run the following commands:
mkdir ~/abc
cd ~/abc
wget https://raw.githubusercontent.com/chrsmj/always-be-conferencing/master/extensions-pngnpbx-abc-v16f.ael2
echo '#include "extensions-pngnpbx-abc-v16f.ael2"' > extensions.ael
echo '[from-internal-custom]' > 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
2. Now you are about to copy the files into the Asterisk configuration directory.
You will probably need to be root or use sudo access to complete this next step:
sudo cp -i ~/abc/extensions* /etc/asterisk/
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. Run this command to check your existing file:
cat /etc/asterisk/extensions_custom.conf
If it is empty, then you can try the copy again, and just clobber the old file:
sudo cp ~/abc/extensions_custom.conf /etc/asterisk/
If the existing file is not empty, then you will need to manually 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 Changes" button to appear, so make a trivial thing like
adding ABC after your name, then "Submit", then "Apply Changes".)
4. Finally, start making test calls from your desk phone, with massive dial strings:
123*2224*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.
To hear your GPS co-ordinates, any participant can press * at any time
during the call. To stop the bot playback, press #.
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:
localhost*CLI> indication add us silent 0/15000
Note this mini-HOWTO assumes all phones are using the same channel technology
(preferably chan_PJSIP but legacy chan_SIP should also work, and maybe others.)
PREREQ: The ASTERISK Extension Language (AEL)
=============================================
ABC is configured in the ASTERISK Extension Language. 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 version of Asterisk, you can run this
command on the Asterisk CLI:
localhost*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-v16f.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:
localhost*CLI> ael reload
localhost*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. This works by adding a ChanSpy() on
the caller.
Tin Can Mode WARNING
====================
There are several potential shortcomings in Tin Can mode compared to Simple
Mode, including the following caveats:
0. In Simple Mode, everyone can always talk to each other.
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 conference.
2. In Tin Can Mode, callers will not get access to DTMF menu options until the
remote end answers. Then, everyone will get access, same as Simple Mode.
3. 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.)
4. 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.)
DTMF WARNING
============
DTMF pass through is currently not tested well. DTMF is restricted to menu
options. (TODO: should the need arise to navigate a remote IVR, you can press 1 then
the number and the single digit will be transmitted: 11 to send 1, 12 -> 2, etc.)
PRIVACY WARNING
===============
The storing of exact GPS co-ordinates of each phone presents multiple safety, security,
and privacy concerns. ABC attempts to solve some of these by only persisting GPS info
in encrypted formats inside the internal Asterisk DB. This prevents bulk dumping of data
via Asterisk CLI commands like "database show" but 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 /var/lib/asterisk/ and the /var/lib/asterisk/keys/
directory in the same tarball.
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 co-ordinates, using the included IVR. 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.
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.
LOGGING
=======
Call Detail Records will be saved in files based on whatever ABC type 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 type 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 235 lines directly into your testing dial plan...
;
; Example #1: Simple Mode
; -----------------------

Frequently Asked Questions
==========================
Question:
What are the conference menu options ?
Answer:
* YOU ARE HERE! Speaks GPS co-ordinates of the caller into the conference.
0 Operator (TODO: Play back all of the menu options. Just to your phone.)
1 (empty) (TODO: Might be option to pass DTMF through and/or mute/unmute)
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 information of caller is spoken into the conference.
8 (empty) (TODO: Might be option for friends to add in a new "T"elephone number.)
9 "W"hat the? Redial the remote destination phone number into the conference.
# Halts any automated message playbacks (may have to press it twice sometimes.)
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:
localhost*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
Please consult your local numbering plan rules before making changes.
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
dispatchable location directions to the nation's critical infrastructure ?
Answer:
Maybe but that is currently beyond the scope of this technical document.
Thank you for reading!
