[Asterisk-Users] ip phones and intercom/paging

[John Todd]

Not with your phones, unless they have auto-answer (and probably not 
even then.)

I have heard of people with phones that support "pager" features on 
the other pair of wires in an RJ-11.  In other words, the second pair 
of wires into the phone carries an audio stream that is played out 
the speaker regardless of the status of the phone.

If you had phones like this, you could use the Console channel and 
the audio out jack on your Asterisk server to pipe the output into 
the phone system, thus creating "pager" calls to all stations.  You 
would not (easily) have the ability to select individual stations. 
You could just as easily pipe this output to your office PA system.
