CU Trade Groups Join in Support of Call-Blocking Notification Codes

WASHINGTON—A coalition of voice service providers has filed an ex parte letter with the Federal Communications Commission expressing direct support of a recently filed letter on call blocking notification codes.

CUNA said it supports adoption of SIP Code (signaling protocol) 608 to provide notification to callers that a voice service provider has blocked their call using analytics.

The FCC permits a SIP Code 603 to be used to temporarily, but currently, its use does not differentiate between calls declined and calls blocked, which is the issue with CUNA said it is most concerned.

The voice service providers concurred with the position taken in a letter from various trade associations that include CUNA and NAFCU that SIP Code 603+—an enhanced version that would indicate a call has been blocked by a voice service provider—can be used in the interim if it meets certain criteria.

Point of Agreement

Both CUNA and NAFCU have said they continue to encourage development of SIP Code 608.

“We concur with the Associations that any 603+ standard must include a number of critical features and functions to meet the Commission’s requirements for immediate call blocking notification when a provider has used analytics to block a caller’s call,” the providers wrote.
