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

[Rüdiger, Christoph]

Hi Carsten,

not quite. I’m looking for a maintainable way of splitting an incoming video into a pure audio call to station 1 (deskphone) and a pure video call or mixed audio/video call to station 2 (softphone). Both stations belong to the same agent though.

Background is that the agents all prefer the hardphones very much over the softphones and hence all have their headsets connected to the hardphone. In the rare case a video call comes in, they should ideally be able to keep using their hardphones for the audio instead of fiddling with their headsets trying to switch over from hardphone to PC while a call is ringing.
Of course, the video stream must terminate on the softphones. The hardphones don’t have video capabilities.

If this is not possible (or maintainable), we must migrate the whole call center to softphones. So, it is kind of a convenience feature and I’m evaluating at which cost it comes.

Regards,
Christoph

Hi Rüdiger,

what you could achieve with Kamailio (and in my understanding, this is what you are thinking about), is to send Audio-Calls to Group 1 (e.g. your legacy agents) and Video-Calls to Group 2 (e.g. Agents with a Video-Phone or Soft-Client). Is this, what you want to achieve?

Thanks,
Carsten

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
