[Asterisk-Users] "Broadcasting" Calls?

[Jeff Maki]

Hey Everybody:

Asterisk is really cool, first off! I'm impressed!

Anyway, I'm working on a design project funded in part by the National 
Science Foundation, and part of the project requires a system that callers 
can call in, and talk to other "teams". That part is easy with Asterisk. 
The hard part is this: the system must also allow one to call the system 
and talk to all teams at once. My question for you is: how can I have 
somebody call in, then have the system call a list of numbers (i.e. the 
other teams) and play to them what the caller is saying?

If that isn't possible, can I have the caller record a sound, then play 
that to the other teams all at once (or one at a time)?

I see there are modules pbx_wilcalu and pbx_spool that look like they might 
do something of the sort, but I can't find any docs on this--I can create a 
new module if there isn't any functionality to do something like this, as 
I'm a programmer, too, but I'm trying to avoid duplicating work already 
done...

Thanks for a cool product and your help,

-Jeff.
