GSM gateway
The S0 port supports the GSM gateway connected to it. Any phone numbers can be used for the connection. They must be entered in the PBX and GSM gateway configurations.
*Note: When you configure the GSM gateway, you must also input the connection type of the ISDN connection.
*Note: GSM gateways accept external phone calls automatically. This may cause call charges for the caller, even if no-one picks up the phone at the internal destination.
*Note: If the PBX is not connected to the land line, outgoing external calls can only be accepted via a targeted exchange line access using the phone numbers entered on the page Routing > VoIP/GSM Routing > Exception numbers (and the corresponding accesses, also configured on this page) or via a configured preferred exchange line (exchange line settings for subscribers or groups).
