T21P E2 Audio Issues

[wilcochris]

Hi all,

I have a very strange issue with my T21P E2 phone that is only fairly recent.

I have it connected to a PoE switch and voice QOS is a priority.

When a caller rings, I cannot hear them speak but they can hear me.

I have reset the phone to factory (I was having the reverse issue until I did this).

Handset volume is at the highest level.

When I first got the phone, this was not an issue at all.

I am at a loss as to what I may be missing and was wondering if anyone had any ideas.

Firmware Version 52.81.0.110
Hardware Version 52.0.0.0.0.0.0
