  • Statement: Today when a service provider returns/donates a thousands-block to the pool and NANPA approves it, NANPA adds the thousands-block to the pool inventory immediately, but with a future “Block Available Date” that must be at least 45 calendar days after the thousands-block’s disconnect effective date entered on the Part 3 approval. This 45-day timeframe is documented in section 11.1.11.5 of the Thousands-Block (NPA-NXX-X) & Central Office Code (NPA-NXX) Administration Guidelines. The 45-day timeframe exists to give the code holder time to make translations updates, if needed, to provide vacant number treatment for the numbers within that thousands-block while the block is in the pool. It is unclear whether code holders still make such translations updates, but all monthly LERGTM Routing Guide recipients can subscribe to the LERGTM One-Day Changes Process at no additional charge. Reducing the 45 calendar days timeframe down to 30 calendar days will make thousands-blocks available for reuse more quickly.
  • Resolution: INC agreed to update ATIS-0300119, Thousands-Block (NPA-NXX-X) & Central Office Code (NPA-NXX) Administration Guidelines (TBCOCAG) To Require NANPA/PA to make disconnected thousands-blocks available for reassignment 30 calendar days after the Thousands-block disconnect effective date, as shown in INC-2024-00081R001. This Issue will be in Initial Pending status until the implementation of the combined NAS.

  • Title: Revise ATIS-1000084.v003 – Operational and Management Considerations for SHAKEN STI Certification Authorities and Policy Administrators
  • Statement: ATIS-1000084.v003– ATIS Standard on Operational and Management Considerations for SHAKEN STI Certification Authorities and Policy Administrators was initially published without any considerations for the Certificate Management procedures applied by the STI-PA in issuing self-signed certificates for ensuring the integrity of the information in the list of Trusted STI-CAs. The certificate used by the STI-PA in signing the information contained in the list of Trusted STI-CAs is used by the STI-VS to ensure that the STI-Certificate, used to sign the SIP Identity header field, was issued by an STI-CA that has been approved to issue certificates in the SHAKEN ecosystem. ATIS-1000087.v002 introduces requirements for the STI-PA certificate management that are applicable to the STI-PA in general and thus should be included in a baseline specification.

  • Issue: 0181
  • Title: Add “iat” and “sub” claims to SPC Token and update allowed certificate signature algorithms and curves
  • Statement: STI-CAs verify that the SPC Token has not expired by looking at the “exp” claim. However, STI-CAs have no way of knowing when the SPC Token was issued. This prevents STI-CAs from enforcing stricter policies, for example, that SPC Tokens must be short lived (e.g., 1-day). The STI-PA could include an “iat” claim which would enable STI-CAs to determine if an SPC Token is short lived or not. STI-CAs are required to put the name of the entity they issued the certificate to in the certificate’s subject organization name. However, in practice this name often does not match the name the STI-PA uses to identify the service provider, which causes confusion. If the STI-PA included a “sub” claim in the SPC Token, the STI-CA could use this name which would ensure the names used by the STI-CA and STI-PA match. The STI-PA already collects the name of each service provider. The US CP allows either ecdsa-with-sha256 or ecdsa-with-sha384 certificate signature algorithms. ATIS-1000080.v005 only allows ecdsa-with-sha256. ATIS-1000080 should not conflict with the US CP. The US CP allows either P-256 or P-384 public key curves. ATIS-1000080.v005 only allows P-256. ATIS-1000080 should not conflict with the US CP.

The committee's consensus resolution concludes its work on an issue unless new or substantive information is brought forth. During the 21 day review period, comments on a consensus resolution may be provided to the committee contact and committee leaders.
• Issue in Initial Pending: Issues previously in Initial Closure for which new and substantive information impacting the consensus resolution has been received. An issue may also be in Initial Pending if output that may impact the consensus resolution is expected from another industry group, regulatory body or similar organization.
• Issue in Final Closure: Issues for which work is completed and the resolution accepted by the industry.
