Abstract

This document describes experiences of operational requirements and several considerations for ENUM-based softswitches concerning call routing between two Korean Voice over IP (VoIP) carriers, gained during the ENUM pre-commercial trial hosted by the National Internet Development Agency of Korea (NIDA) in 2006.

Abstract

   This document describes experiences of operational requirements and    several considerations for ENUM-based softswitches concerning call    routing between two Korean Voice over IP (VoIP) carriers, gained    during the ENUM pre-commercial trial hosted by the National Internet    Development Agency of Korea (NIDA) in 2006.

   These experiences show that an interim solution can maintain the    stability of ongoing commercial softswitch system operations during    the initial stage of ENUM service, where the DNS does not have    sufficient data for the majority of calls.
