At Head Office ,Cisco call manager express version 4 is running in core router and also tftp and dhcp server both are running in same router.I mean IP phones are getting IP and downloading phone firmware from CME router.Now what we are looking to implement that want to add some IP phones at branch office under the same CME.Branch office is connected with Head office through VPN having good bandwidth. For that we have to configure Phone IP and TFTP IP address manually. Can You any body guide me how do I do that one?

Lookinh for kind guidance.
