If you have the responsibility to design, upgrade and manage data networks to carry IP Telephony (voice, video and data); need help in evaluating competing IP-Centrex and IP-PBX systems; or need guidance in specifying the parameters for a service level agreement for IP-Centrex, this unique reference provides you with the knowledge you need to get the job done right. 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.

This unique resource helps you present your company’s telecom capabilities, and offers a better understanding of the pluses and minuses of competitive sales presentations. It includes summary descriptions of 14 IP telephony systems on the world’s market, while clearly identifying the advantages and disadvantages of IP-Centrex. There are detailed financial analyses of three realistic case studies, together with descriptions of how Centrex is used in various organizations.
