I have a customer that has two buildings that are connected with a fiber link. We have a single Asterisk server to cover both buildings. Now the customer went and bought an overhead paging system for the remote building and they want to integrate it with Asterisk. Is there a device that can connect over IP or an ATA that has an audio output port? The buildings are about 500 meters apart so we cannot run a cable from one building to the other just for audio. -- Telecomunicaciones Abiertas de M?xico S.A. de C.V.

Polycom phones have a paging feature which is basically just auto answer on speakerphone. I suppose it would be quite easy to wire up the headphone jack on the Polycom to the Bogen (or whatever). A Polycom 301 should work just fine. If I were you, I would try that (but I have two or three 301s just laying around...) Thanks, Steve Totaro
Something like this should work.... http://www.voipsupply.com/product_info.php?products_id=3517&osCsid=85766c1b3901219249d6fdea9bc7b7c0 On 9/4/07, Carlos Chavez <cursor at telecomabmex.com> wrote:> I have a customer that has two buildings that are connected with a > fiber link.

You can use an inexpensive PC with a sound card. Install Asterisk on it and set an extension that calls /dev/dsp. This will send audio out the speaker port on the sound card. Setup a trunk between this unit and your primary Asterisk server and you should be in business. Bryan M.

Most of the overhead paging systems I have worked with had an CO input, which worked with the FXO port on an ATA. A couple brands had multiple source options, it is worth checking, I had problems with poor audio quality using the sound card with asterisk.

I used a Viking PI-1 unit connected to the amp and a SPA-3000 connected to the viking. This gave me overhead paging and ringing. It did require a little tweaking on the SPA side because the PI-1 only provides 12V instead of the normal 48V to CO port. It's been working fine since it was put in about 8 months ago. I think the Viking unit was about $120. More info in it here: http://www.vikingelectronics.com/products/view_product.php?pid=199# -Dave
