Can I have Call Manager setup for Branch offices via ISDN line ?
Posted on 2009-04-22
I have Head Office (HO) and 50 Branch offices, at the moment Call manager is configured only in HO, but I want to integrate the branch offices and want to deploy the cisco IP phones on each site. I know to integrate them via Data network (MPLS, DSL or other internet connection), but I have no idea how to connect all the branch offices through ISDN line, as we have ISDN calls free and I want all 50 sites phone communicate and get registered to the Call Manager. I want to setup this like its been setup via Data Network!
Reply will be appreciated.
