Loop Through
The Vigor2100V/VG series have a “Line” port on the rear
panel for connecting to a PSTN (regular analogue) line.
The Loop Through option can be used to set an alternate
telephone number for your contact on the PSTN, which the
Vigor2100V/VG series will dial instead of the SIP account if
you lose broadband access or power to the Vigor2100V/VG
series.
Hence, the PSTN line can act as a lifeline (backup
mechanism) for VoIP calls. The default is VoIP mode. The
lifeline mechanism is activated automatically if you specify
“PSTN” as Loop Through and enter Backup Phone
Number.
