When the Vigor IPPBX is powered OFF, is the analogue telephone port [Phone] connected directly to the incoming PSTN [Line] so it will continue to work in an emergency?

This is the std behaviour on many other PSTN VOIP adapters (e.g. Linksys SPA3102). Does the Vigor do this?

Yes. Analogue line failover works as you would expect.

Brilliant, thanks for that. I'm liking the Vigor IPPBX more and more.
