The sound is played but I did not hear

Hello,

I have another little problem with my ZAPs channels, in fact, when I received a call, I heard no sound while in the CLI, sound is played:

Here is my setup:
Zapata.conf:

Zaptel.conf:

What is the recording format of the file you are playing. Have you tried using the echotest application to see if that works?

recording format : gsm.

using SIP, I heard the sound
