That being the case, maybe a pcap of the audio might yield some clues? On Wed, Apr 1, 2009 at 3:34 PM, Thorhallur Sverrisson <thorhs@basis.is>wrote:
The Polycom 650 is an IP phone, so the ground loop should not apply. Ground loops occur only in analog systems.
As to what the buzzing is, I'm not sure. I have performed tests using Polycom 650s with out any sound artifacts. In fact the 650 audio has been flawless in my testing.
Sorry I don't have a solution, just wanted to steer you away from a ground-loop debugging session.

Cheers for the replies. I'm not sure if I'm replying properly but here goes.
I'm using Polycom 650 phones.
I'm not really sure what a 60hz ground loop is so will need clarification, sorry I'm new to this. The phones are all on the same LAN and the conferencing is done on internal calls.
Cheers
