It enables you to more accurately estimate the time and resources needed to implement IP Telephony in your organization. The book describes the IP-Centrex option of having the telephone company take responsibility for the service delivery and offers the kind of information service providers need to improve marketing and sales campaigns for IP-Centrex services
