Hello @washaq

Please note that the RTP ports should be open for UDP and not TCP. Also 5060 and 5090 should be open for TCP and UDP. Make sure that the firewall checker located on the dashboard of the 3CX management console passes all tests and try the call again.
Have a look at the following link that contains all the necessary info

Under extensions > Options do you have PBX Delivers Audio checked?

it is not checked, but problem solved by forwarding correct ports.
