The Federal Communications Commission has denied a petition from USTelecom seeking flexibility on how and when they would notify callers—including those in the accounts receivable management industry—that their calls were blocked. ACA International secured language in the Telephone Robocall Abuse Criminal Enforcement and Deterrence (TRACED) Act and in previous FCC orders requiring notification to callers when carriers were indiscriminately blocking calls using their analytics.

In addition to advocating for SIP Codes 607 and 608 in the meetings with the FCC, ACA and the joint industry trade groups also called for the commission to sunset the use of SIP Code 603, which only signals to the caller that the recipient declined the call, not that the call was subject to blocking by voice service providers.
