Multiple RTCPeerConnection in the same session

[tomasek]

Hi guys, i am new to the WebRTC party and i am trying to solve a problem for a few days.
I need to create an User-Agent using JsSIP. I need it to communicate with my Application Server and all that seems to be working. I have Kamailio as a webRTC gateway (my AS works only with UDP) and Coturn to handle the ICE part.
All goes well when it's basic calls. when i attempt to add an MRF in between, it fails miserably 😞
When holding, my AS connects the holding party with MRF, to have a comfort annc. That seems fine, but the holder gets disconnected.
After some review on the current JsSIP's code, it seems that it is not creating a new RTCPeerConnection when there's the hold reinvite.
I get it, it works as expected when there's no AS adding an MRF there.

After the background story, my question here is: Is it possible to hold different RTCPeerConnection objects, so the #A and #B connection is still open while the holding party is listening to the comfort annc?
That should be a different RTCPeerConnection and what i see is that it just updates the RemoteDescription with the MRF's SDP
