asterisk users - Sep 2004 - IP Intercom's

Im looking for an Intercom solution thats interoperable wit Asterisk. Ive
read several posts about people using the 2nd lines on some SIP phones
w/speaker phone. Unfortunatley I dont that is going to cut it in a large
warehouse enviroment. Does anyone have a solution that uses a
"loudspeaker" ?

Thank you,
Steve Maroney

There are several ways to approach this:
* modify an existing SIP phone with Auto-answer (Grandstream for example) to
interface with a loud
speaker
* use a SIP client (Asterisk for example) on a small PC and interface the sound
card to a
loudspeaker
* use a traditional overhead paging/intercom hardware and interface to it via
the sound card  or via
an FXS port.
* use an analog auto answer door phone with an FXS interface

The easiest way is to hook up loud speakers to the sound card of the
Asterisk box. I use this and it works pretty well.
