We have tested the Grandstreams off-site, fed by fiber providers; no problem.
It's difficult to troubleshoot remotely, even with access to the C6220 as things change for unknown reasons; after a power failure and reboot, it changed for the worse. A Poly SIP phone is now incapacitated as well, signaling but no audio.
We'll have someone on-site in a few days. But the better overall solution looks like getting the customer to abandon DOCSIS and move to fiber; it's available, dependable, and no more expensive.
Ok, thanks for the feedback.
Hope you can get it working.
Good Luck.
