[SIPForum-discussion] How to find packet is SIP or RTP

[mohit]

Hi,

I have a doubt that by looking at the UDP packet, how to find out if the
packet is SIP or RTP. We cannot use destination port info as some
servers may use port other than 5060 (Default port for SIP).
What field should be used while parsing the packet to identify if packet
is SIP or RTP?

Regards
Mohit.
