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

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