asterisk users - Mar 2005 - Global Intercom on SIP phones

Hello Everyone,

I would like to create an Intercom extension that will dial a group of
extensions which are connected to SIP phones. The SIP phones are setup
to auto answer a particular extension assigned to one of the lines in
the phone.  All phones must answer and broadcast the page message at
the same time.

Has anyone done this?  Or  should I install an overhead speaker system
using the oss/alsa console as a broadcast. Can the local port be set to
auto answer calls?

Thank you,

Max W. Blackmer,  Jr.
