You were right the first time....it is a Charter problem. You are not getting enough voltage from their modem.

I had a KXTA824 on a cable modem (TWC) that false rang, it was erratic output of the modem. Got TWC to change their modem....problem gone.

The key is you can call out but the ring is the problem. Sure, the modem test okay...because they have fluctuating load from the node.
