Caller to my digital home phone gets 2 rings on his end followed by dead air

Others in my neighborhood have the same problem.  I have a ticket M63848724 opened 1/21/2023.  I'm in NC. Callers from Florida, SC, NC, and NY have told me they have the same issue - call my digital home phone, get either dead air, or 2 rings followed by dead air.  Two reports of going to voicemail, but not mine - a computer generate message - not my home phone voicemail or my AT&T voicemail.  All options in phone settings have been attempted, including turning off call protect (originally got JSP 500 error, then one day it was off, and now it's off and can't be turned on - JSP 500 error trying to turn on.)  I've used quick assist to connect to the Florida account, pinged, tracerte'd and telnet'd to the VOIP server specified in my BGW320-500, all of which were successful.  (No way to trace from FL voip server to mine, but irrelevant since problem occurs from other states as well.)

Anyone else having this problem?
