Electronic Number Mapping: An Enabler for Shifting Voice Traffic to IP Networks14 June 2005
An increasing number of remotely operating U.S. companies are upgrading or converting their telecom infrastructure to conduct voice calls over IP networks using the electronic number mapping (ENUM) protocol. ENUM does this by enabling dedicated voice over Internet protocol (VoIP)-to-VoIP calls and facilitating switched circuit networks to send data over the IP networks.
The new analysis from Frost & Sullivan (www.telecom.frost.com), U.S. Electronic Number Mapping Protocols Market Insight Outlook, reveals that there is a renewed interest from carriers and service providers to use ENUM for dedicated IP to IP communications.

One of the immediate applications of ENUM is voice over Internet protocol (VoIP), by enabling the transition of voice traffic from the legacy public switched telephone network (PSTN) to the Internet. Telecom companies can in fact create their internal versions of the domain name system (DNS) and then use a private implementation of the ENUM protocol (called carrier ENUM) to assist in routing telephone calls through their own IP networks.
These cuts cost telecom companies as well as VoIP and cable operators in the form of access fees for using the PSTN and enables improved IP-to-IP communications. Individual telecom companies especially inter exchange carriers (IXCs), can cut down on reciprocal access fees by bypassing local exchange carriers' networks.
"ENUM could initially see widespread adoption, with large and medium-sized corporations seeking to reduce telephone costs by using VoIP for voice calls," says Frost & Sullivan Industry Analyst Piyush Arora. "Corporations could even implement ENUM entirely behind the scenes and route some phone calls over the Internet instead of the switched telephone network."
Apart from saving cost, a leading advantage of ENUM will be the convergence of voice traffic presently conducted over PSTN and IP networks. Currently, VoIP-to-VoIP calls route through the PSTN, which is less efficient than direct VoIP-to-VoIP calls.
Deploying VoIP-related services requiring end-to-end IP connectivity is not possible while such calls route through the PSTN.
"ENUM provides a scalable solution for maintaining end-to-end IP connectivity and could emerge as an important enabler for VoIP as the technology enters the mainstream," notes Arora. "ENUM also facilitates the PSTN to VoIP calling; hence, it provides an efficient way to transition traffic between the traditional switched circuit and the IP networks."
Telecom carriers seek a simple addressing mechanism to help them deploy IP-based services such as multimedia messaging service (MMS), push-to-talk, and session initiation protocol (SIP)-based voice service.
They also need to be able to implement these services across different technology environments such as global system for mobile communications (GSM), code division multiple access (CDMA), and fixed-line. ENUM makes all of this possible.
"This ability to develop a simplified addressing mechanism across multiple technology platforms and portability regions or countries, in turn, facilitates cross-operator deployment of IP-based services," comments Arora. "U.S. wireless carriers are already using private ENUM to enable inter-carrier routing of MMS messages that need end-to-end IP connectivity."
U.S. Electronic Number Mapping Protocols Market Insight Outlook, part of the Telecom Services 9707 subscription, examines the status of the ENUM protocol with a focus on its benefits, drawbacks, major applications, and upcoming trends. It also discusses the possible impacts that ENUM can have on the telecom industry and the status of carrier ENUM and public ENUM in the United States. This research enables companies to align their positioning strategies to benefit from the changing markets and obtain maximum return on investment. Analyst interviews and executive summaries are available to the press.
