Hi Adham
RTP is a packet format for multimedia data streams. It can be used for
media-on-demand as well as interactive services such as Internet telephony.
RTP consists of a data and a control part. The control part is called
Real-Time Transport Control Protocol (RTCP).
1- match protocol rtp : match even-numbered UDP ports in RTP packet and does
not identify the odd-numbered ports that RTCP packets and that RTCP packets
run on. so it will match the actual voice payload but not the control.
2- match ip rtp [starting port numbre] [port range] : this will match all
the specified pots ranges RTP and RTCP.
3- Also will match the specified UDP ranges ( all of them ).
please see the link for more details
