I'm looking into connecting our Definity Gs31 R11 switch to on e of our branch which they are using a 3com NBX over our VPN. I already have a CLAN card and a MEDPRO. We would like to dial by extension on the NBX server and have them dial us by extensions. How would I accomplish this matter. I know we have to creat router patterns and all the other stuff. I major concern is to have both systems talk to each other over VPN.
