Wireshark · Wireshark-users: [Wireshark-users] One port not available in SIP/SDP packets

[vishal borkar <weeshalll@xxxxxxxxx>]

Hi all .

A few days back i was sniffing the data using wireshark .The communication in question was a Yahoo VoIP call between me and my friend.

I observed that the port on my system where the actual RTP data was flowing was nowhere to be found in the

SIP/SDP packets.Can anyone explain to me  as to why this might be happening ? 

Thanks in advance.
