Before you move to Voice over IP have these bases covered
EdgeCore just moved office buildings and I was put in charge of setting up the network and phone systems. A couple of the guys recommended VoIP. It sounded like a good idea at the time. So I went along with the recommendation. I got a quote from 8x8.com and everything looked good. My next step was to call up the local utility company and get an internet connection that would support VoIP. The local utility company recommended the 8mb down and 1.5mb up for voice over IP for $80 a month.
