Paging with IP Speakers

Has anyone had expierence with IP Ceiling Speakers? Some online sites are now offering VoIP Ceiling Speakers and I am interested to know if anyone has worked with these.

Do they work as well as | better than | worse than traditional proprietary paging systems?

How would you configure Asterisk for these?

When I asked a co-worker a similar question, he told me to check out some Bogen products ( I noticed that they have a few devices that might work, but I think that all of them will be more expensive than the option shown at VoIP supply. has a page devoted to this question too (

I’m going to need to find some sort of solution to this problem, sometime in the next couple of months, so be sure to post with what you decide to do, and how it works.
