CP960 Static noise for offsite meeting attendees
Has anyone had any issues with a CP960 unit where the audio for the offsite/remote attendees starts off fine but then turns into static/electric noise?

The setup:
CP960 HD IP conference phone with CPW90
Firmware: CP960- (pushed from Vonage)
CP960 connected to laptop via USB (USB hub/dock)

The meetings start off fine, audio sounds great, but then 5-10 minutes in the audio for the offsite/remote attendees goes to static and they can't hear voices clearly. The problem goes away once you unplug the USB and plug it back in.

The CP960 is setup as a SIP endpoint, Vonage, and being used as a UC device via USB. We haven't see this issue when using it as a SIP endpoint but haven't had too many voice calls on it either the majority of use is as a UC device.

I've replaced cables (ethernet and USB) and USB hubs and have had reports of the same issue no matter how I've had it connected. I've also done a factory reset on it and am still having issues.

It looks like Vonage has another firmware option for it that I may test out next, but that seems to be an older update: CP960-

I'm starting to think it's a bad unit and I need to get a replacement unit.
