I have never implemented a voip solution and was wondering if anyone could list the basic cisco components that I will need. My situation is thus: I have a customer that wants to pull out his old pbx at one of the remote sites in favor of a voip solution. The data network is a star with t1 lines to and fro the corporate center. It is all cisco. Basically I dont know what I will need at the remote site and the central site in order to make this happen. thanks, eric
