[A*UG] Overhead paging solutions?

[Carey Jung]

We're currently doing intra-office paging via Meetme conferences and the
auto-answer feature available in Polycom phones.  You dial a paging
extension, say something into it, hang up, and it broadcasts the message to
all the phones.  Works great so far.

We have a prospect who also needs overhead paging via their existing paging
speakers.  Does anybody have any experience with such systems or
recommendations on how to integrate Asterisk with overhead speakers?

Thanks,
Carey
