No audio when calling to an Avaya phone

[rramlal]

Hi,

I have this setup:

1. Centralised multisite running CUCM 6

2. branch sites A and B get services of main CUCM 6.

3. branch site C has a voice gateway connected to an avaya phone system using H323.

What works:

1. Branch A and B calls are successful

2. Branch A to C successful

3. Branch B to C unsuccessful. Call is seen as ringing with no audio and then connects to the avaya extension voicemail with no audio.

I ran a debug for calls from branch A and B and they are the same. I have attached the configs below. Any ideas why this may be happening?

If branch C users can hear branch B users & Not vice versa ( i.e. one way audio ), do you have the route in place for Branch B users ?

Perhaps you had one for Branch A but missing for Branch B ?

Lemme know how it goes.
