    The issue is in the logs as:
    No RTP packets were received:remoteAddr=,extAddr=,localAddr=

    The RTP packets carry the voice and this is usually associated to a firewall issue. You need to run the firewall checker after having configured the firewall to forward the needed ports. You may also need to do the same or simply turn-off the Windows firewall.

    You can find the port forwarding guide by doing a search in the 3CX site.

    I am not familiar with the GSM gateways you are using so while it appears that the issue is still the firewall, I suppose that perhaps issues may still be associated to the hardware and its set-up.
