Video works when A calls B not when B calls A

Hi there,

I posted this also to the FreePBX forums, as I am not sure whether the issue is related to Asterisk or FreePBX.

If my video intercom (ext 8001) calls my laptop (ext 8005), the call includes video and all works well. But if I do things the other way around (laltop calls video intercom), the call does not include video. I have included the debug info below showing the call without video.

I can see an error in there:

No joint capabilities for ‘video’ media stream between our configuration((h264|h263p|h263|h261)) and incoming SDP((ulaw|ilbc))

BTW, since I am using PJSIP, I needed to manually enable video for each extension by setting each extension’s Allowed Codecs setting to ‘h264&h263p&h263&h261&ulaw&alaw&gsm&g726’. In other words, I needed to explicitly list h264 in there to get any video working at all.

Any ideas?

Thanks,
Pete

Have you read about the Codec negotiation process ?
Codec negotiation

When Asterisk is receiving a call, the codec will initially be set to the
first codec in the allowed codecs defined for the user receiving the call
that the caller also indicates that it supports. But, after the caller
starts sending RTP, Asterisk will switch to using whatever codec the caller
is sending.

When Asterisk is placing a call, the codec used will be the first codec in
the allowed codecs that the callee indicates that it supports. Asterisk will
not switch to whatever codec the callee is sending.

Thanks for the info.

I’m still not sure why there is no video since both extensions support H.264 and both extensions have h264 listed as the first codec in their respective allowed lists.

Maybe I am missing something?

BTW, with Chan_SIP this worked fine, but since switching to PJSIP the video only works when initiated from the video intercom.

Cheers.

The information described earlier has been taken from sip.conf sample file, Related to pjsip I havent found any information about the codec negotiation, So we must assume that is the same process , and if not I hope some thoughts from the experts

Asterisk will prefer the codec selected on the incoming side for the outgoing side, at least for audio. I’m not sure that there is that deep support for video codecs.

I believe the “Dahua UAC” is broken in its support of SDP. We offer the first stream as audio, and the second stream as video. They answer with the first stream as video and the second stream as audio. This is against the SDP RFC and the SDP negotiator in PJSIP actually follows it. There’s no real way to fix it, except for hacking up the PJSIP SDP negotiator to support this broken device.

Thanks for the info, Would it make sense for Asterisk’s PJSIP to support this ‘swapped’ order of audio and video streams? I wonder if there are other products out there that also offer video as the first stream.

They aren’t offering video as the first stream. They are ANSWERING video as the first stream, when we have offered audio. That’s the wrong part. The order of streams matters. It would not be easy to change this.

Ah OK. So it would be best for me to contact Dahua and hope that their developers can fix this in order to the follow the standards.

It would be easier than trying to change the PJSIP SDP negotiator to work in such a case.
