asterisk users - Jul 2007 - Single ringer phone for incoming calls, that every one can answer

Setting up pick/callgroups really tightly is the way to go - one of our
techs here does that all the time for clients.

Tom, 
Let me recap what you want, do you means that the you allow to answer an
trunk incoming call but not extensions call.
Now, we can have either 
1) Set the difference ringing tone on your telephone, which you have to set
the new context, Alert-info, and depending on your SIP phone set. 
2) Use the SLA (Share Line Appearance) phone, where it's blink on your SLA
LED when an incoming trunk line call. 

I say IF or maybe, 
If you can make the incoming call set to difference tone to identify the
calls, and it might help to modify the source-code or add the new feature
code into your dialplan. Some thing like "linepickup".

I will say, most of such demands is being solved by the phone ringing tone
at the moment.


Good luck.
