I wrote that dissector, so....

In one word, yes. If traffic to this ip adddress / port combination is 
found, the packet is dissected as RTP or RTCP. Both protocols need a 
call to rtp_add_address or rtcp_add_address!

There's also a minor bug in both the dissectors, I think it's related 
to padding or something. But because the contents of the packet are 
displayed correctly fixing the bug doesn't have a high priority ;-)
So far I haven't been able to find it :-(
