Track channels through Asterisk Management Interface (AMI)

Project description

Cacofonisk

Cacofonisk is a framework that connects to the Asterisk PBX, listens to events on the Asterisk Management Interface (AMI) and tracks the status of calls currently in progress in Asterisk.

Cacofonisk takes a stream of AMI events as input and uses these to keep track of the channels currently active in Asterisk and how they are related. When something interesting happens to one of the channels, it will call a method on a call state Reporter with interesting information about the call, like who is in the call, and a unique identifier.

This data can then be used to send webhooks regarding a call, to notify a person who is being called, or to log calls being performed.

Status

This product is actively being developed and used at VoIPGRID.

Usage

Requirements

  • Python >= 3.4
  • Panoramisk 1.x
  • Asterisk >= 12

Installation

Cacofonisk is available on Pypi so you can easily install it with pip:

$ pip install cacofonisk

To install the dependencies from source:

$ python3 setup.py install

Running

To run Cacofonisk, you will need two things: a Runner and a Reporter.

A Runner is a class which is responsible for passing AMI events to the Cacofonisk. Two runners are included: an AmiRunner (which connects to the Asterisk Management Interface) and a FileRunner (which imports AMI events from a JSON file).

A Reporter is a class which takes the interesting data from Cacofonisk and does awesome things with it. You can find various Reporters in the examples folder.

To create your own reporter, you can extend the BaseReporter class and implement your own event handlers, like so:

from cacofonisk import AmiRunner, BaseReporter


class ReportAllTheThings(BaseReporter):

    def on_b_dial(self, caller, targets):
        target_channels = [target.name for target in targets]
        caller_number = caller.caller_id.num
        print("{} is now calling {}".format(
            caller_number, ', '.join(target_channels),
        ))

    def on_up(self, caller, target):
        target_number = target.caller_id.num
        caller_number = caller.caller_id.num
        print("{} is now in conversation with {}".format(caller_number, target_number))

    def on_hangup(self, caller, reason):
        caller_number = caller.caller_id.num
        print("{} is no longer calling (reason: {})".format(caller_number, reason))


reporter = ReportAllTheThings()
runner = AmiRunner(['tcp://username:password@127.0.0.1:5038'], reporter)
runner.run()

This reporter can then be passed to a Runner of your choice to process AMI events.

For more information about the parameters of the reporter, please see the docs in BaseReporter.

You can also listen for UserEvents using the on_user_event function. This can be used to pass additional data from Asterisk to your Cacofonisk application.

Running the tests

To run the test suite:

$ python3 -m unittest
