Hi!! Martin, Im calculating the delay as u hav told, I have another question about it: Do I have to take timestamp of sending original report always as 0.0 secs? Because If i dont do that I get a negative value. I apply the filter rtcp in wireshark so that i can only see rtc

Aha! ok now I get it. Its actually the 13 ms which is the actual network propagation delay then 13 ms is quite an acceptable value. The values for delay which I had sent u are from the books which Im using as reference. The authors are all german a Mr. Mathias Hein (Voice over IP Professional Se

Ok!! I tried out with the view option and it works. Im surprised that its so easy to do it and I was using these complex calculations all the time. So 1932 ms is the round trip delay of the packets u sent me. Isnt it a high value coz wat I read round trip delay (d) should be less than 150

Just choose 'View | Time Display Format | Seconds since previous Displayed Packet', and you'll see that they are 1932ms apart. (I can't follow your calculations where you try to convert the absolute time to milliseconds - you don't need to do this). Martin On 5/22/07, Eram Khan <[EMAIL PROTECTED

Hi!! Martin, well your explanation was quite helpful but I still have some queries. I used your 2 frames to do the delay calculation, I still get a negative value. Maybe I am not calculating it correctly. Im using the 2 frames u hav send to show it to u, maybe u can detect my mistake: De
