Hi Ron,

Yes, all of this can be done without too much hassle.  I am assuming at 
each local site you will have IP/soft phones connected to that asterisk 
box, so each local astreisk box will have it own local users. Yes, than 
The voicemail will sit on each local asterisk, becuase the user is 
defined there.

Your concern with the dialplan is, i assume, is what numbers are local 
numbers, inter branch numbers, and what numbers must go the the main * 
server.  If you use DUNDI, this will sort out the interbranch numbers, 
since each * box will advertise its local numbers to other asterisk 
servers.

One question, can each of the local @ servers 'see' each other, or can 
they only 'see' the main server, because this will change your dialplan.
