asyncio powered FreeSWITCH cluster control using pure Python 3.6+
switchio (pronounced Switch Ee OoH) is the next evolution of switchy
(think Bulbasaur -> Ivysaur) which leverages modern Python's new native
coroutine syntax and, for now, asyncio.
API-wise the project intends to be the flask for VoIP but with a focus on performance and scalability more like sanic.
Build a routing system using Python's new coroutine syntax:
from switchio.apps.routers import Router
router = Router(
guards={
'Call-Direction': 'inbound',
'variable_sofia_profile': 'external'},
subscribe=('PLAYBACK_START', 'PLAYBACK_STOP'),
)
@router.route('(.*)')
async def welcome(sess, match, router):
"""Say hello to inbound calls.
"""
await sess.answer() # resumes once call has been fully answered
sess.log.info("Answered call to {}".format(match.groups(0)))
sess.playback( # non-blocking
'en/us/callie/ivr/8000/ivr-founder_of_freesource.wav')
await sess.recv("PLAYBACK_START")
sess.log.info("Playing welcome message")
await sess.recv("PLAYBACK_STOP")
await sess.hangup() # resumes once call has been fully hungupRun this app (assuming it's in dialplan.py) from the shell:
$ switchio serve fs-host1 fs-host2 fs-host3 --app ./dialplan.py:router
You can also run it from your own script:
if __name__ == '__main__':
from switchio import Service
service = Service(['fs-host1', 'fs-host2', 'fs-host3'])
service.apps.load_app(router, app_id='default')
service.run()Run thousands of call flows to stress test your service system using the built-in auto-dialer:
$ switchio dial fs-tester1 fs-tester2 --profile external --proxy myproxy.com --rate 100 --limit 3000
pip install switchio
Oh we've got them docs!
- Enable inbound ESL connections
- Add a park-only dialplan (Hint: we include one here)
See the docs for the deats!
- A slew of built-in apps
- A full blown auto-dialer originally built for stress testing VoIP service systems
- Super detailed ESL event logging
Have an idea for a general purpose switchio app or helper?

Also, if you like switchio let us know on Riot!
switchio differentiates itself by supporting FreeSWITCH
process cluster control as well as focusing on leveraging the
most modern Python language features. switchio takes pride
in being a batteries included framework that tries to make all
the tricky things about FreeSWITCH a cinch.

If you'd like to record performance measurements using the CDR app, some optional numerical packages can be used:
| Feature | Dependency | Installation |
|---|---|---|
| Metrics Capture | pandas | pip install switchio[metrics] |
| Graphing | matplotlib | pip install switchio[graphing] |
| HDF5 | pytables [1] | pip install switchio[hdf5] |
| [1] | pytables support is a bit shaky and not recommended unless
you intend to locally process massive data sets worth of CDRs.
The default CSV backend is usually sufficient on a modern file
system. |
