[Asterisk-video] chan_sip dumb mode/ passthrough patch?

[hyrth at web.de]

Hi,

we have a test-account at a VOIP/SIP Provider and would like to make video-calls from and to 3g handsets.

In the case of incoming 3g video-calls the provider is not demultiplexing the data, he is simply transferring it in CLEARMODE - as explained in RFC 4040 http://tools.ietf.org/rfc/rfc4040.txt  (they have a SIEMENS system there).

The SDP looks like this:
...
m=audio 18026 RTP/AVP 91 8
a=rtpmap:91 CLEARMODE/8000
a=rtpmap:8 PCMA/8000
...

That's actually fine, so h324m_gw could do the demultiplexing.
The problem is that chan_sip cannot simply transfer the data - it is trying find a transcoder or whatever.

Does anybody know a patch for chan_sip, so that it simply transfers the rtp packets?

Best regards,

Hrvoje
