SIP-RTMP gateway dosn't work corecctly with Smile CTI Server.
Developers of this server says that problem is that siprtmp violates rfc3261:
branch-id in ACK Via field for 200 OK response must not be identical to 
branch-id of original INVITE
How to fix this?

---
One option is to modify UserAgent's createRequest method in
http://code.google.com/p/p2p-sip/source/browse/trunk/src/std/rfc3261.py r64 
after line 1052
as follows
if method == 'ACK': Via.branch += 'ack'
