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:

I have the following log from 3CX:

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