A reference for those who are responsible for designing, upgrading and managing data networks to carry IP telephony (voice, video and data); or for those who need help in evaluating competing IP-Centrex and IP-PBX systems; or for those who need guidance in specifying the parameters for a service level agreement for IP-Centrex. The authors seek to enable you to estimate more accurately the time and resources needed to implement IP telephony in the organization. They describe the IP-Centrex option of having the telephone company take responsibility for the service delivery and they offer information for service providers on improving sales and marketing campaigns for IP-Centrex services.
