SIP is pretty easy. Normally it uses 5060 port. But prioritizing this port traffic won't enhance the overall voice quality. RTP ports are decided dynamically during SIP handshake. To filter RTP protocol from packet pattern will delay the traffic. So using port number is easier way, BUT, you need to find out these ports from the SIP handshake messages. How to prioritize depends on your setup's capabilities. -----Original Message----- From: lartc-bounces@xxxxxxxxxxxxxxx [mailto:lartc-bounces@xxxxxxxxxxxxxxx] On Behalf Of Beat Meier Sent: Friday, October 12, 2007 7:48 AM To: lartc@xxxxxxxxxxxxxxx Subject: Filtering RTP/SIP protocol (Voip)? Hello How can I filter (i.e. priorize) RTP protocol and SIP? Has anybody wrote a filter for that in the meantime (In 2006 there was none answer from the list ...)
