I would tend to agree with Dave, a cheapo FXO card will give you a 600 ohm ouput which will be fine to connect directly to a Paging Amp input. You really don't need a large amp to do this. I used to buy amps from radio shack that we installed in Shoppers Drug Mart for just this purpose. If you plan on more than a few ceiling speakers or horns then you will have to go with a 70v system where each speaker has a transformer attached but for just 4 speakers you can use 8 ohm speakers that are very cheap and work well.

But External paging systems are pretty affordable and they tie into Asterisk with either and FXS or FSO interface. I'm not sure if you're doing it for fun or for profit but you might find less headaches with an external system. One of the issues one customer had with a Nortel BCM, and I'm not sure if this also applies to Asterisk systems is that the invites were sent sequentially and so some phones would only catch the latter part of the page. It just took a few or several seconds to setup all the sessions to 50+ phones and the receptionist wasn't waiting that long. I don't even know if she got an indication that the channel was ready for her to page. On 5/12/06, Tony Davis <[EMAIL PROTECTED]> wrote: > > Anyone have any luck in setting up multi-device paging?
