Sonus Networks Adds Support for ENUM

Sonus Networks has added support for the Electronic Number Mapping System (ENUM) to the latest release of its IP Multimedia Subsystem (IMS)-ready network solution. ENUM is a number mapping system designed to streamline the convergence of IP-Based voice networks with the Public Switched Telephony Network (PSTN) and facilitate seamless IP-to-IP peering.

ENUM allows telephone numbers to be routed through IP-based architectures such as IMS using a Domain Name System (DNS)-based architecture. ENUM and DNS-based architectures can facilitate interoperability for a wide range of applications including IP-voice video, presence, and instant messaging. ENUM is a standards-based protocol resulting from the efforts of the Internet Engineering Task Force's (IETF's) Telephone Number Mapping Working Group.
