Operating
The Fallback function gives access to use both the
PSTN and GSM for emergency calls. Set one as a
priority and the other one works as fallback in case
the prioritized one fails (the function requires that
both phone line and GSM SIM card are active).
Enable Fallback through SafeLine CONNECT or SafeLine Pro. When
activating Fallback, both systems have to be operative. Incoming calls
are handled by both interfaces, but will not be used simultaneously.
The chosen interface is locked while in-/outgoing calls are ongoing.
Note: when Fallback is active, phone numbers’ prefix is filtrated
automatically (e.g. 0*0890510 becomes 0890510). This lets the same
configured number be used for both PSTN and GSM.
