The Internet engineering community has developed a technology that lets you type a telephone number into your Web browser and find a corresponding URL, e-mail address or IP address. Called Enum, the new technology integrates the world's telephone numbering plan with the Internet's Domain Name System (DNS) to power a new class of online telephony services. The Internet Engineering Task Force (IETF) published its Enum specification as a proposed standard in September. Last week, Telcordia Technologies and VeriSign announced the first large-scale test of Enum services. And network vendors such as Cisco, Lucent and Nortel Networks are expected to ship Enum-compliant products next year. Why all the buzz about Enum? Because it's considered a key enabling technology for the anticipated convergence of the public switched telephone network and the Internet.
