asterisk users - May 2007 - asterisk setup for church / conference call / speaker system integration

We have several people in our church that recently became disabled. I am 
thinking of setting up an asterisk server and several phone lined so 
that they can call in to church during services to listen to the service.

The phone lines at church are also used by our private school during the 
week.  So I am thinking that I need to setup a schedule so that the 
lines used for the service will automatically go to the conference 
during normal service times and ring the phones the rest of the time.

We have 2 analog lines currently,  DSL is available, and I'm checking 
now to see if we can get a voip provider that will provide 3 - 10 local 
numbers.

to connect to the speaker system I either need to trigger a ring on a 
analog line to the phone interface on our speaker system, it picks up on 
the first ring, or we can manully push a button that picks up the line. 
If we do the second we would have to have something in asterisk connect 
it to the conference when it picks up.

the next consideration is that sometimes we might want to connect out to 
a conference call from another church. so we need to be able to dial out 
from one of the phones and then somehow trigger the speaker systems 
incoming side to pickup. ( I just thought of it now - I suppose a call 
transfer to that line would be all thats needed for that)

If it were me, I would:

1. create a conference room
2. create a .call file that dials into the speaker system
3. create .call files to dial the participants, muting them

This can obviously be scripted very easily. A simple cron job copying the
.call files should do nicely. If the disabled persons wish to no longer
participate, you can simply delete that .call file; conversely, if you need
to add someone, you can just create another one. Then you won't have to
worry about incoming phone numbers and coordinating with the private school,
you can bring it in when you need it, etc.
