asterisk users - Jan 2008 - is Power fail transfer possible with asterisk?

Hi.  I have a client who wants some way that his analog phones can
call out even after the power is out and the UPS has died -- some way
that a phone can connect directly to an fxo or some such when power is
gone.  Any hardware around which can do this?  I have heard of some
ATA's which do this, do any of the channel banks have this capability?

Thanks.

you spend it?

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.

1) If his phones are this critical, he needs a triple redundant generator.
2) Ask him what he would like to do after 36 hours of power outage, when
even the telco stops being able to provide battery on their POTS lines.  If
your provider is out, there's very little you can do.  Perhaps a ham radio
attached to a car battery?

Speed costs; how fast would you like to go?

When I saw the subject I thought the poster was maybe asking if was possible to
transfer the live RTP stream from one Asterisk system to another in the event
that power was lost....

There is ATA boxes with a port that you connect to a analog line and
when SIP fails to register will it use the analog port. Some ATA boxes
routes emergency calls direct to the analog port.

I think that Sipura SPA-3000,
 http://www.sipura.com/products/spa3000.htm
will cover your needs.

No need to be rude Mr Tilghman, try to be constructive.
