    Dear forum members,

    We have a problem with incoming GSM calls to 3CX PBX.

    In any case incoming calls are dropped by 404 User Unknown error.

    I try to reach extension 402, IP of PBX : 192.168.0.103, IP of GSM Gateway : 192.168.0.106

    The GSM Gateway is registered as a gateway. Outgoing calls are working fine.

    Config of GSM Gateway: [​IMG]

    I have the following log from 3CX:

    Yes, I have checked it, but the incoming number can be different.
