The company has a white paper on VoIP I thought you would be interested in because as you know making informed decisions requires educating yourself. Part of the white paper is a table explaining how to deploy VoIP depending on your individual requirements such as a greenfield environment or new one.

I suggest you read all the white papers that apply to your situation. There are some real gems in here.
