What’s “PSTN life line” and “ISDN loop through”?

PSTN life line and ISDN loop through are backup mechanisms for voice communication in the event of Internet access failure, VoIP unreachable or manual configuration. In other words, the Vigor2500V series provides users three possible lines to implement their voice communication, i.e. VoIP, PSTN and ISDN. The users can choose any one of these three selections by manual configuration or automatic detection to dial out a phone call.
