asterisk users - Feb 2006 - Replicating functionality from our prior PBX

We have just installed Asterisk in our new office and we have some 
teething problems, but so far nothing we did not
expect/could not handle.  However, our CEO was very attached to a 
function in our old Nortel PBX that I am not sure
how to approach.   If someone could point me in the right direction, I 
would be most grateful.

The function is this:

CEO records message, then specifies a list of extensions for that 
message to be sent to....

Any thoughts, questions, comments would be appreciated.

Thanks,

Patrick Foster
