[Freeswitch-users] Capturing the Current Call Audio

Sat Sep 12 01:27:59 MSD 2015

And from the cap file I can get the audio right?
I’m taking a look in some scripts that can extract the audio from pcap files, but I think it’s need to be embedded on the pcap file when it’s saving right?

I tried the sngrep and it generated a 128k pcap file, and I did about 3 calls, does it really have the audio?

(I’m about to test pcapsipdump but the installation is failing in OS X, I think I will move to a CentOS machine)

Thank you all guys!

The main problem is that the script calls the execute record as a synchronous way, but I would need to do some actions while it's recording like play sounds, curl posts etc.
