no audio in incoming call on dahdi channel

Postby mqacim » Tue Oct 20, 2015 5:34 am

Hi all!

I'm using Digium TE110p PCI card for PRI E1 line. I have done the configurations of dahdi. I can call out from the PRI using a softphone also I can call into PRI from an external phone or mobile. When I dial a number from PRI end softphone, I can hear audio on both ends and it is working fine. But when I make a call from mobile and answer it from PRI end softphone, i can hear the audio coming from softphone on mobile but cannot hear audio from mobile on softphone.

Any suggestions why this is happening?

I'm from Pakistan, could not find what to use in loadzone, so left it at default.
