i have a file that is a real time call, definitely it contains the information
of sending time and receiving time of a packet. i am calling the time that a
packet took from caller to callee as "network delay". and its kind of general
thing, not for a specific group of packets (like SIP, RTP etc)
my idea is to find the over all time that a packet take from caller to callee.
the intermediate hopes (UAS caller side, UAS callee side etc) are kind or
irrelevant.
i am interested in the time that a packet takes from UAC(caller) to the other
UAC(callee), they could be registered on same UAS or different.

hope my statement is clear now
