## Overview ##
This project implements a SIP stack and provides tools for holding SIP media sessions with other SIP speakers. It is written entirely in Python using standard libraries with support for python 2.7 and >=3.5, and attempts to provide a dead-easy and idiomatic API for python clients.
There is an iPython tutorial to get started with at SIP Party tutorial.ipynb. Docs are generated using sphinx but still a work in progress.
Tested on CentOS 6 and the latest Mac OS X public release. Windows support is unlikely.
Clone from github, cd to the root directory and install the requirements using
pip install -r requirements.txt
If you want to edit and build the docs, use
pip install -r docs_requirements.txt
as well.
Create a SIP 'party' and start a phone call. The most basic party is the one that doesn't actually advertise any media.
from sipparty.parties import NoMediaSimpleCallsParty
party = NoMediaSimpleCallsParty(aor='alice@atlanta.com')
dialog = party.invite('bill@biloxi.com')
dialog.terminate()
Very flexible API for configuring objects using the sipparty.deepclass.DeepClass class.
from sipparty.parties import NoMediaSimpleCallsParty
party = NoMediaSimpleCallsParty()
party.uri = 'sip:alice@atlanta.com'
# Is the same as
party.aor = 'alice@atlanta.com'
# Is the same as
party.username = 'alice'
party.host = 'atlanta.com'
# Is the same as
from sipparty.sip.components import URI
party.uri = URI(aor='alice@atlanta.com')
Creating multiple parties with the default settings only results in a single listen socket.
from sipparty.parties import NoMediaSimpleCallsParty
from sipparty.sip.siptransport import SIPTransport
parties = [
NoMediaSimpleCallsParty(aor='test%d@test.com' % (test + 1,))
for test in range(100)]
map(lambda x: x.listen(), parties)
# The transport is implemented using sipparty.util.Singleton which
# provides a powerful and simple Singleton design pattern implementation.
tp = SIPTransport()
tp.listen_socket_count
> 1
Dialog state is maintained by inheriting from the sipparty.fsm.FSM class, allowing for easy debuggability of state changes and understandable exceptions when an illegal input is applied in a given state.
