Registration Failed errors

[dmillar]

Starting a few nights ago, we are nightly getting the following errors for 3 sites we host from the same server and provider:
Registration at Telnyx - compnayA has failed. Destination (sip:192.76.120.10:5060;lr) is not reachable, DNS error resolving FQDN, or service is not available.
I don't what the cause is or what log to look at for more information.
Is anyone out there able to point me in the right direction?

Hi @dmillar

It looks like something is causing the registration to fail but that could be due to a number of reasons. Does this happen during the day as well? Do you miss any calls or any outbound calls fail?
You will need to run a packet capture to determine what is happening exactly with the registrations. A 3CX partner could help you determine the issue.
