[Freeswitch-users] advise to troubleshoot a call

[Michael Collins]

pcapsipdump ftw!

Check it out:
http://wiki.freeswitch.org/wiki/Packet_Capture#pcapsipdump

It gets pcaps for you and separates each call into its own file with both
signaling and media. Find the pcap with a bad phone call and open that one
up in Wireshark for analysis.
