Hi,
I'm fairly new to 3cx as a sys admin and I worked to upgrade the system from version 11 to 15 back in February, following the recommended upgrade path and not going from 11 to 15 directly.
All of the trunks worked perfectly well up until 3 weeks ago. I was forced to change the trunks from FQDN to direct IPs which is not ideal.
The server has been set to use Google IPs all along, and I am able to NSLOOKUP all 3 trunks and can PING all 3 trunks using their FQDNs.
But when checking the dashboard while test calling, I consistently run into this error:
Call or Registration to 1800xxxxxxx@([email protected]) has failed. 0.0.0.0 replied: 503 No DNS results; warning: No other DNS entries to try (0,0); internal
This happens for my NexVortex and FreeConferenceCallHD trunks as well. They only work if I switch them to a direct IP.
Just not sure what could have suddenly cause this "break".
Thanks in advance for any help or suggestions.
