Hi Harold, I'm currently using SIP MESSAGE as you suggest. I'm finding that it is not ideal since there can be considerable latency in the relay of SIP messages when a particular user has registered multiple times within the registration timeout period. (e.g. forcfully restarting the client app). I'm hoping that someone can chime in about switching to RTCP or RTP for message passing. Any thoughts on this?
