[asterisk-users] is Power fail transfer possible with asterisk?

[John Novack]

There have been transfer switches available since the dawn of Telephony, 
( well, at least common Battery Telephony ) that will do just that.
Look around, ask a real telephone man, or use Google.

Or, use a simple DPDT relay run off any power source that fails when you 
want to make the transfer.
