In late 1999, the LNPA WG, now known as the Number Portability Industry Forum (NPIF), established a “Problem Identification and Management” process (PIM) for Number Portability (NP) issues. The group, made up of Number Portability Industry members, developed:
The NPIF is not responsible for resolving all NP problems. The NPIF performs an initial evaluation of each problem/issue submitted, then either develops a resolution for the issue or refers it to the appropriate forum for resolution. Issues submitted (PIM) are tracked in the PIMs Tracking Matrix.
Issues should be submitted to the NPIF using the Problem/Issue Identification and Description Form, at least two weeks before the NPIF meeting at which Number Portability issue's discussion is desired.
