[asterisk-users] sometimes half audio on 7960

[Jerry Geis]

Hi,

I am getting half channel audio on cisco 7960?
Any idea why? Details below.

Jerry


This same phone has been working for MONTHS using a TDM2400p
with no issues.
Today we got a T1 installed coming into Box A with all incoming calls 
going to Box B (the TDM2400P box).
The TDM2400 is no longer in use. All incoming and outgoing calls are 
done with the T1 and Box A and Box B
use SIP between them (will change later).

I have 6 polycom phones that work perfectly in this arrangement. I have 
1 cisco 7960 that gets half channel audio.
The calling person can hear the called person but that is all.

Where do I start looking for something like this?

Again the 7960 has been fine for 2 years using the TDM2400p.

Doesnt seem to matter if calls are coming into the 7960 or if this 
person is calling out. The same half channel exists.

THanks for hte help.

Jerry
