ATIS Gets Consensus on VoIP Call Routing

Members of ATIS, the Alliance for Telecommunications Industry Solutions, and other industry organizations it brought together in a workshop last month, concluded that a unified approach to intercarrier VoIP call routing was both necessary and possible.

ATIS announced its plan this week to achieve a standardized approach to the challenge. In addition to ATIS, workshop participants from the CC1 ENUM LLC, the Third Generation Partnership Project (3GPP,) the GSM Association and the Internet Engineering Task Force (IETF) agreed network interconnection architectures could be implemented to achieve a unified call routing solution.

In order to assess whether a common call routing solution is suitable, ATIS established the Inter-carrier Call Routing Working Group (IVCR-WG), which will examine the Centralized Upper Tier Registry (CUTR) model that was developed as a result of the ATIS-commissioned IVCR Focus Group. The IVCR-WG will analyze the CUTR for domestic and global scalability, flexibility to adapt to new service requirements, and its ability to meet performance expectations, such as support for high-volume bilaterals and reasonable query response times. Discussion and work within the IVCR-WG will begin immediately with results of the analysis anticipated to be available in the third quarter of 2008.

“ATIS members and industry representatives are committed to introducing efficiencies of call routing without compromising business opportunities. The development of an interoperable IVCR solution solves a critical industry-wide problem,” stated Susan Miller, President and CEO of ATIS.
