My understanding is that you MUST use TCP and an NSStream for your "control" connection, that is the connection that you use to rendezvous with the server, send keepalives, get notices of incoming calls, etc. However, for the actual call itself, you'll have an audio session keeping you alive and therefore can use UDP and plain sockets for the call.
