Call Scenarios
Using the PSTN-Gateway for 311 and 911 Calls
To implement this scenario, add the rule “[39]11<:@gw0>” to Line 1. When the user dials 311 or 911,
the call is routed to the PSTN gateway.
Note If the PSTN Line is busy after the user dials 311 or 911, the call still fails. For true life-line supports,
therefore, the PSTN Line cannot be shared.
Auto-Fallback to the PSTN-Gateway
To implement this scenario, enable <Auto PSTN Fallback>. When registration fails or link is down, the
SPA3102 automatically calls “fallback@gw0” when user picks up Line 1. The SPA3102 does not reboot
when the link is down. However, the SPA3102 reboots when the link is back up and Line 1 and PSTN
Line are not in use.
