CUNA urges FCC to require purpose-built call blocking notification methods

CUNA discusses 603+ Standard with FCC chairwoman’s office

July 8, 2022

This week, CUNA continued its discussions with the FCC regarding minimum technical standards for an interim call blocking notification mechanism. CUNA and other associations met with staff from the office of Chairwoman Rosenworcel to discuss the technical specifications the associations had shared with the ATIS/SIP Forum NNI Task Force this spring on Wednesday. 

“We have been informed that standards-setting bodies are advancing a 603+ standard and have prioritized its completion ahead of the 608 standard—even though the Commission has not approved 603+ as a permanent solution, and despite the Commission’s expectation that development of 608 proceed with all deliberate speed,” the letter reads. 

“The Associations continue to believe, consistent with past submissions, that SIP Code 608 remains the most effective means to provide timely, actionable notification of analytics-based blocking consistent with the TRACED Act and the Commission’s previously articulated priorities,” it adds. 

A recently filed ex parte letter describes the conversation with staff of the Chairwoman’s office. The group had recently shared these technical specifications with the FCC’s Consumer and Governmental Affairs Bureau. The technical specifications identify several necessary functionalities for an enhanced SIP Code 603 (called 603+), should the FCC order that the code will be used to provide notification on an interim basis.
