I believe a more accurate measurement would use hardware timestamps at receipt instead of the timstamps inside of the messages. You can look at a different set of numbers using that method here. http://new.maystreet.com/app/sipdiff This shows the variability and a higher average.


The unexplained part in the above link could be related to where the timestamps are taken, if its in the application layer then the additional time could be related to time spend in network buffers before data is sent out on the network.
