Re: [Freeswitch-users] Buzzing when people speak in conference

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. Thorhallur Stromin Normin wrote:

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
