[SR-Users] Split audio and video into different calls

[Henning Westerholt]

Hello,

AFAIK there is no support in rtpengine for video codecs yet, e.g., refer to this discussion: https://groups.google.com/g/rtpengine/c/Tf3us2oBW3w

You can of course route the calls with video differently with Kamailio, for example with sdpops or other detection mechanism. And then using one of the mentioned other PBX projects to process the call.
I would probably try to handle the video call media completely on the PBX then, and not try to mix and match somehow it on the different components. Especially as its only a low percentage of the total calls.

Cheers,

Henning

Subject: [SR-Users] Split audio and video into different calls

Hi everyone,

we are running a call center with really good to use hardphones and audio only up to this point. Because of changing regulation, we soon have to deal with video calls as well, but only for a fraction of the calls (below 1%).

Instead of switching everyone to clumsy softphones for the rare case of a video call, I’m exploring the ability to branch an incoming call into a pure audio call to the hardphone and optionally a pure video call to the softphone.

Has anyone done this in the past and can share some experiences/ideas on

a)       Can it be done purely with Kamailio and rtpengine? I don’t have a clear picture of how to do it purely with Kamailio on the SIP side, because we end up with two independent legs (to the hardphone and the softphone). Or do I need to deploy an Asterisk, Yate, freeswitch, etc. and doing it as a 3-way conference where one party gets both RTP streams (the trunk) and the other two parties only get one RTP stream (either audio or video)?

b)      Was it worth the effort or a steady candidate for troubles?

I’m looking forward to your thoughts, especially on question b).

Have a nice weekend,
Christoph
