how to analyze udp streams of skype chat

[Vineeth <grittygeek () gmail com>]

Hello all,

I have a capture file of a group chat in skype between three persons. I 
have to measure the latency of the packet from source to destination and 
for which I need their time stamps. I see that all my voice chat follow 
the udp protocol and I am not able to find their time stamps. I just 
find the arrival time of the packet and not the time at which the packet 
was send from the destination. I believe the udp message must be 
converted to RTP in order to do this analysis am I right? If not can 
some one tell me a better way?

I am basically trying to collect a real time data of how users chat when 
it comes to a group conversation.

I am attaching the captured file with this email. Any help is appreciated.

Thank You

Vineeth
