[Asterisk-Users] POTS fail-over?

[Matt McIntyre]

I would just go with your first idea. Just find a cheap low current
mechanical relay with two sets of poles in normally closed and normally
open positions. Use your wall wart to energize the coil when power is
available. Wire it so that your "emergency phone" is tied to the CO in
the normally closed position so when the power fails and the relay coil
is not energized, the phone will be switched from being connected to the
Asterisk box and be directly connected to the CO line.

Do it by hand in the wiring closet with a patch panel and some short
cross
over cables.

Getting all my pieces in place for asterisk.  Does anyone know of a POTS
fail-over device, that will allow me to access my (only) landline on an
extension in case Asterisk fails?  My current PBX patches CO1 into Ext4
when there's no power.  If there isn't anything out there, I'll just use
a relay with wall-adaptor, but I was hoping that there's something a bit
more elegant out there.  Yes, my * machine will have UPS -- this is for
extended outtages.
