[OpenSIPStack] By Looking at the UDP packet, How to find out if Packet is SIP/RTP

[Ashish K. <ash...@gm...>]

Hi Joegen,

I ahve one query.
By Looking at the UDP packet, how to find out if the packet is SIP or RTP.
We cannot use the destination port information as the there are no standard
fixed port for SIP/RTP. Although the Default port for SIP is 5060, but still
some servers may use different ports.
What information you use while parsing to identify if the packet is SIP or
RTP.

Please reply.

regards
Ashish
