VoIP Workshop The INC VoIP Workshop is creating a comparison matrix examining why or why not various subject areas are of concern.

LNPA Workshop Issue 359 – “Adding Full NXX Request to Part 1A” was tabled. The decision made by the FCC on Change Order 11 will indicate to INC how to proceed on Issue 359. Issue 369 – “Forecasting” remains tabled pending FCC decision on the NANC Numbering Oversight Working Group (NOWG) recommendation regarding PAS forecasts.

CO/NXX Workshop INC in conjunction with the NANC LNPA Working Group has completed its work on the Code Holder/LERG Assignee Exit Procedures. Included in these procedures is the following assumption: If there are no active or pending ports on the returned NXX code pending disconnect, the NPAC will use the Part 3 disconnect information received via email from the NANPA to remove the capability to port numbers from the returned NXX code 15 business days prior to the effective date of the disconnect. This removal will cause any new port attempts against the returned NXX code to fail at the user interface, thus avoiding additional impediments to the code return process. Since INC views this as a policy decision, INC requests that NANC concur with the above assumption and so note it in today’s meeting record. This concludes INC’s work related to the LNPA Working Group’s PIMs 14, 15, 20, and 21.

DMM Workshop The INC is struggling to develop an administrative process in order to coordinate publication of INC guidelines with the approval of system changes resulting from NANPA/PA change orders. Implementing guideline changes when there are outstanding change orders has created problems If change orders are approved and implemented, resolutions may no longer apply or may adversely impact current procedures If change orders are not approved, INC may need to cancel or rework active related issues
