Good evening.
We have a Hosted 3CX v20.0 Update 9, PRO edition, we had some test extensions fully working. inbound/outbound calls working. We hired a local 3cx support partner to do some general configuration, setup and support. One of their support personally accidentally sync'd the whole M365 environment and sent invitation emails to everyone. To roll this back, instead of deleting the 300+ generated extensions they restored a 3CX backup, I can only assume it is the nightly backup we configured. After they restored the backup our system will no longer register with our carrier. I've gone back and forth with the carrier and they say we are not sending any registration requests since the PBX restore. PCAP shows up sending, but no return traffic from the carrier. However in our 3CX event log I see this;
Event ID 12293
Registration at <name> SIP Provider has failed. Destination (sip:x.x.x.x:5060;lr) is not reachable, DNS error resolving FQDN, or service is not available.
In the PCAP I see 408 Request Timeout.
When I disable Registration in the trunk settings the trunk shows up, but of course calls are rejected because registration is required.
Our phones are registering to 3CX, any diagnostics I run seem to be good. I don't have shell access to the hosted environment to run nslookup to make sure DNS is resolving, but from what I can tell the DNS servers are 8.8.8.8
SIP registration username and password verified, carrier even changed the PW and gave us a new one.
