Call issues

[levilund]

Hi there,

I'm currently experiencing issues with our 3CX where if we call a different number that is being hosted by us on 3CX I will get one ring but then there will be complete silence at the end with no indication that there is a call ongoing. It does however work if I call from a mobile or if I call a different number on 3CX that isn't being hosted.

I've checked the PCAP and at least on 3CXs end the call connects, inside of the PCAP you can hear complete audio.

If I remove our trunk and readd it then it works temporarily then resorts back to this issue.

Do things begin working properly again if you shut 3CX down, then restart?

If you have not yet done so, run the 3CX Firewall checker, to be certain that all required ports are open. If you have access to it, check the 3CX Activity Log, set to Verbose, for clues, as to what might be happening.

No rebooting 3CX doesn't resolve the issue unfortunately.

Firewall checker is passing completely and verbose is acting as if it is working fine.

Any issues with split DNS and the phones used to make/receive the call?
