Slight correction.  Rather than twisted/protocols/sip.py, you probably want
to use the protocol code from Divmod Sine.  There is some effort to backport
improvements and fixes to Twisted, but this is still in progress, so you'll
be missing out on a ton of stuff if you use what's in any existing Twisted
release.
