SIP Proxy on Twisted
Pythonists are aware that there is such a miracle library for working with network protocols like Twisted. It is a bit complicated at first, but after enlightenment it becomes an absolutely necessary tool.
In the standard package it comes with many already implemented protocols - IMAP, XMPP, HTTP (in combination with URL processing and some template library is a very useful tool), etc. The number of protocols that are implemented on / for Twisted is incalculable.
I found SIP among the standard protocols - it was last updated 3 years ago, there is a Shtoom VoIP phone project, which also stalled. Nevertheless, here is a Twisted recorder for you:
')
And what is most surprising is that it works. At leisure, I want to try to make the simplest SIP-phone, it will be interesting. I will call it Shtoom ressurection, it will not even have the functions of its predecessor, and it will die on version -0.1, wait!
For home reading - blog by Andrei Smirnov . I like this particular link, since newbies often skip the Deferred theme, and it’s very vain to write with Twisted without it.
