A coalition of voice service providers filed an ex parte letter with the Federal Communications Commission Friday expressing direct support of CUNA’s recently filed letter on call blocking notification codes.

CUNA and other organizations continue to support to adoption of SIP Code (signaling protocol) 608 to provide notification to callers that a voice service provider has blocked their call using analytics, they wrote to the Federal Communications Commission Wednesday.

The Federal Communications Commission (FCC) should require voice service providers to transition to the use of specific codes to notify callers of a blocked call, CUNA and other organizations wrote to the FCC Tuesday. This includes providing a specific date to use the required codes.

The Federal Communications Commission should delay implementing its call-blocking deadline, CUNA and other organizations wrote in an ex parte letter filed in response to a petition regarding requirements that voice service providers that block calls notify callers of the block using certain codes.
