What kinds of applications could use ENUM?
The core applications ENUM will focus on are Voice over IP (VoIP) and Voice Profile for Internet e-mail (VPIM). The goal of the VoIP industry is to be able to make simple and high-quality voice calls using IP networks. The VPIM industry wants to develop voice mail systems that can exchange messages over IP networks. ENUMs applications will most certainly reach beyond VoIP and VPIM to such services as internet fax and Instant Messaging.
