ISSUE: Randomly occurring one-way audio with phones on Sophos Switch.
We have no errors logged on Sophos switches or XGS, no dropped packets. Pathway is GIG.
Our users have random one-way audio on Avaya IP phones H323. This occurs when the phones shuffle, (Extension to Extension call).
The issue occurs with phones on Sophos switches.
The issue began shortly after installing Sophos switches. We have other offices with Avaya Phones, Sophos XGS, and Extreme Networks switches and they do NOT have this problem, same pbx. OpenOffice is located at central location.
I have done the following so far:
Tweaked QOS on switches - NO change. Also we have ample bandwidth so QOS really shouldn't make or break.
Today, after reading Avaya troubleshooting I disabled extension to extension direct. We will see what difference this makes.
IF anyone has any ideas, please comment.
