This is my scenario: I have a sip client in my Mobile phone, but no video support. For a video chat, i want to use my mobile for audio and video should be displayed in laptop.
I was curious whether using GRUU concept, can i make both the devices to participate in a call. Such that, my Mobile phone would carry m=audio & a=sendrec. But Laptop, only Video - m=video, a=recvonly. I just wonder is there any feasible way to make this scenario to work.
