RTP call flow discrimination

0

Hi all,

What about two RTP flows (two calls: another call just a few seconds after the first call with the same caller-callee) with the same IPs and ports (is it possible ???):

first call (at time t): caller: IP:192.168.100.6 port:3000 <-> callee: IP:192.168.100.7 port 12687

second call (at t+10 second, for example): caller: IP:192.168.100.6 port:3000 <-> callee: IP:192.168.100.7 port 12687

In this case, how to descriminate both flows ... ???

thanks for your help

From RFC 3550 section 5.2: "In RTP, multiplexing is provided by the destination transport address (network address and port number) which is different for each RTP session." So no, they must be unique for each individual session.
