Dear 3CX Team,
We are currently having some issues with our self-hosted 3CX appliance. We are running version 20.0 Update 6 (Build 724).
When forwarding the call to an external number, we are unable to hear any voice in both directions. We do not have this issue if the call is answered internally from a 3cx agent.
Also, when the call is picked up by 3CX we are unable to hear any prompts uploaded by using the appropriate audio converter.
We did not make any change or modification before these issues showed up and we were previously able to hear prompts and hear external calls.
We have tried restarting the 3CX services multiple times.
Our outbound rules that have worked fine so far are the following
We have also tried running the firewall checks for any misconfiguration, however despite not seeing any denies on our firewall, the checks report that ports 5060 and 5090 are not reachable. However, the ports are open and listening correctly and I can connect to them from a PC that is outside of the local network of the machine hosting the 3CX application.
During a call, we also verified that ports 9000+ open correctly.
What is left out at this point are the failed checks on 3CX PhoneSystem 01 SIP Server and 3CX PhoneSystem Media Server, which I suspect to be the root causes of the issue.
Is there anything else I have not addressed yet?
