asterisk users - Dec 2005 - Announcement only Devices that work with Asterisk for Dedicated 24/7 Conferencing

Does anyone know an IP Phone or Device  that works with Asterisk as an
announcement only device with a loud speaker and that is online forever
and will not hungup for any reason and even if it hangsup, it will
reboot itself to connect to a VOIP Server with a given configuration to
receive the voice data stream. 
 
I have the requirement for a few hundred such devices for a conferencing
application that keeps relaying a conference proceeding all the at a
remote unattended location, without hanging up. If there is  a hangup of
the phone it should reset itself again to rceive the stream again from
the Asterisk server.
 
Any information on such a device is appreciated.

For starters, an old fashioned cassette player that holds the button
in with auto reverse will do, since when the power is out it will
still play it. Connect that to an ATA (radio shack sells a plug that
will connect to a phone line and take the input of a regular headphone
jack to the phone line). Take any ata and configure it as a hotline,
put the cassette player with a regulare analog phone on the port of
the ata, make sure the phone is off hook, so that the ata makes the
hot line call, and viola you are in asterisk. Of course other ways to
do it is: to use an external pager (bogan makes one), that allows
external MOH, and that uses a FXO port that you make sure asterisk
always keeps off hook.

 voipsupply.com has ceiling mounted voip enabled loudspeakers that I
saw on their site maybe not less than a month ago. It's conceivable
with a little dialplan work that you could do what you're looking to
do with that.
