[Freeswitch-users] Convert pcap file to wav file

[Giovanni Maruzzelli]

Google around again, you will find something.
>From wireshark gui interface, you must save the rtp streams and then
convert. You will probanly find a script to do exactly that.

You muat pay attention that your pcap file contains the rtp streams too
(not only sip signaling).

Anyway, this is a question you would better asks to the wireshark mailing
list, is not a quewtion related to FreeSWITCH.
