PCAP made it
Once we have the PCAP, finding a problem is becoming almost a pleasure. Because the files are small, and everything is in the same place. It becomes easy to find jitter problems, missing RTP packets and so on. Last week I saw how another external tool took the PCAP idea to the next level. Using an Ethernet switch with port mirroring, all the traffic that hits the PBX also hits the monitoring server, which also sorts the traffic by calls and then puts them into different files. There were nice logs of SIP packets, RTP analysis and other things you want to know about a call.
