i am using asterisk version 13.28.1. connected to the operator over sip.
I have successfully registered with my provider and getting incoming calls as well.
now issue is in hearing the audio at end user.
I can see the rtp packets are being sent to the MGW of operator, but he says call is silent.
I tried with both NAT Enable and disable. No firewall or selinux running on the machine.
Can anyone suggest on this??
