Hi Kundan,

I've been been performing some more tests with your SIP-RTMP gateway.
Today I've experienced a crash which I thought i should share with
you.

While in the middle of an active call the siprtmp.py process crashed.
This was the traceback:

User._listener exception (<type 'exceptions.AttributeError'>,
AttributeError("'Header' object has no attribute 'branch'",),
<traceback object at 0x883f8c4>)
Traceback (most recent call last):
 File "/home/tom/p2p-sip-read-only/src/app/voip.py", line 280, in

   self._receivedRequest(m, uri)
 File "/home/tom/p2p-sip-read-only/src/std/rfc3261.py", line 434, in
_receivedRequest
   branch = r.first('Via').branch
