One way audio problems are usually, but not always, the result of a firewall or router configuration issue. You will need to provide more information about the hardware you are using, confirm that the 3CX firewall test passes, and check any anti-virus/firewall programmes you have running on the PC.

Ensure that your Windows Firewall is OFF, them run the Firewall checker, it sounds like a firewall matter (router). Make sure that you configured at least port 5060 TCP/UDP and 9000-9049 UDP to forward to the server, if you have a static IP address (public that is), turn off STUN on the server and enter that instead manually.
