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

[Rüdiger, Christoph]

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

  1.  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)?
  2.  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
