What does "PSTN life line" perform on Vigor2100V and Vigor2100VG?
The Vigor2100V and Vigor2100VG 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 and Vigor2100VG will dial instead of the SIP account if you lose ADSL access or power to the Vigor2100V and Vigor2100VG. Hence, the PSTN line can act as a lifeline (backup mechanism) for VoIP calls. The lifeline mechanism is activated automatically but can also be manually configured.
