I have a client who has 6 sites which are all connected via Point-to-Point T1's. Each site has a 1821 router that terminates the point-to-point T1. Each site needs about 5 phones. I was thinking of putting a UC560 at the main and having the remote sites register to that single UC560. I know that the UC solution is for up to 5 sites, but would this setup be considered a single site? Any help would be appreciated.
