 Hi Lars!

  I am also looking for this information. As I told you in my previous email that I am running wireshark on both end than i guess I can calculate the delay. I am in process of reading RFC3550 but if you give some additional information, reference or example how to do it. That will be very nice.

 Thanks alot.

Regards,

Sajid
