Chris,
What you're talking about is exactly what I'm looking for. I'm interested in the middleware that would sit between the speakers and the IAD. I have found the Bogen TAMB device -- however I was wondering if anyone had any experience with this box. How many speakers can you power off of the unit without needing an external amp, etc...

All,
I am currently implementing a VoIP PBX, and need to deal with the paging situation. I would prefer to do paging via overhead speakers.
My plan is to connect a "Paging Unit" to an FXS port of an IAD, and assign
an
extension to that port. I would then simply be able to call that
extension, and
have my call patched through to the overhead speakers.
Has anyone implemented this type of setup, if so, what type of paging unit
did
you deploy, did you require an external amplifier or power supply, and how
many
speakers were you able to connect to the unit? As it stands, I will need between 4 and 8 speakers, and some of the speakers will be 400 feet from
the
main telco closet.
Any thoughts, comments, and suggestions that you can shed on this topic
would be
much appreciated. If you have other methods of implementing overhead
paging, I
would also be interested.

The Valcom units don't mention SIP... they must be some proprietary protocol, also says it's Windows based... eww...
Anything that you can do to an FXS port on a regular PBX you should be able to do to the FXS port of an IAD (within reason of course). You don't usually connect the speakers directly to the FXS, usually there's a device like an inline power supply that provides voltage and audio to the speakers or bullhorn...
The GrandStream HT486 has a nice intercom function which sends a "BEEP!" before answering. The SPA-2000 also has an intercom but doesn't provide the beep...
