3CX and Yeastar TG100 GSM Gateway

[willardc]

Hi everyone

I have a cloud 3CX in AWS.

I have an on prem GSM Gateway Yeastar TG100 with one SIM Slot

I have integrated the two using SIP trunks connections.

I have done some port forwarding on the firewall no traffic is being blocked on the Fortinet firewall side (INBOUND and OUTBOUND RULES.)

Incoming is working fine but outgoing it gives a false ring without ringing to the other end you just get the ringback as if the number is not being picked but nothing is being sent.

Below is what I am getting. Please help

Gateways should only be used with an on premises system, and not with a hosted or cloud system.

Only FXS gateways can be connected to 3CX via the SBC, Not FXO or GSM gateways.
