Hi all, I was wondering if there is any mechanism in SIP to set up a multimedia session where each media is sent/received from/to a different IP peer (identifying the same SIP user). Let's imagine that A wants to establish a multimedia session with B providing different media (audio and a slide-show for example). B is registered in 2 different locations (B1 & B2) where B1 only supports audio and B2 only has the slide-show capability. In this case there will never be a full 2-media session between A and B, although B's locations could handle both streams together.
As far as I understand, SDP does support different IP addresses through a combination of c=/m= lines. That could be fine for a kind of SIP-enabled media controller that wants to get a media locally and another one on the device it controls, but I don't see any way of doing that between independent SIP devices. Do I miss something? I see some solutions mainly using a B2BUA, but they are all much more complex and inadequate...Isn't there any lighter alternative? Thanks for your comments/suggestions.
