It keeps a pool of usable RTP ports, and when it needs to listen for RTP, it chooses one from the pool. There is no specified need for the port to remain the same or differ between dialogs, or even within one dialog (when a re-INVITE is done). > if we know how it is supposed to function we will be better at getting > our systems to work with it. Every time the UA receives SDP in an initial INVITE or re-INVITE, it needs to check the ports specified in the SDP to see what ports it should be sending RTP to for that dialog.
