I have a client with central office and they want to have IP phone setup in two seperate cities. I have never installed voip system but I do have solid background with networks and vpn. Pkg I'm looking at is 4 incoming trunks, 8 digital stations, 2 ip licenses, 2 analog stations, 8 voicemail boxes. Which type of BCM50 do I need to install this setup, regular, adsl router or ethernet router? I would appreciate any help you could give me.
