wireshark network analysis
Posted on 2014-03-09
I'd like the capture the latency for VoIP traffic at each device. In other words, if you look at my setup below, I'd like to capture the packet timestamp from the VoIP phone1 to router1, from router1 to router2, and router2 to phone2. How will I do that?
I know that I cannot capture the VoIP traffic with Wireshark on PC1 because PC1 is behind phone1. So I think I have to use port mirroring on router1. In that case, all I can see is the timestamp for the traffic between phone1 and phone2. Any thoughts will be greatly appreciated. Thx
