• Under 47 CFR 64.1200(k)(3) a terminating provider may block voice calls without liability when blocking uses reasonable analytics designed to identify unwanted calls, those analytics consider caller ID authentication information where available, and consumers may opt out with sufficient information to decide. in context
• A terminating provider that blocks under an opt-out or opt-in analytics program must, on the subscriber's request and at no additional charge, give the subscriber within 3 business days a list of blocked calls to that number with date, time and calling number. in context
• When a caller makes a credible showing that its calls were erroneously blocked, the terminating provider must promptly cease the blocking. in context
• Under 64.1200(k)(11) a provider may block without offering an opt-out when reasonable analytics, including caller ID authentication information where available, show a call pattern highly likely to be illegal; the conditions include human oversight and ceasing the blocking once it knows the calls are lawful. in context
• 47 CFR 64.1200(k)(5) prohibits a provider from blocking a voice call that is an emergency call placed to 911. in context
• A terminating provider may not charge callers for reporting or resolving blocking error complaints made in good faith. in context
• A terminating provider that blocks calls under 64.1200 or uses caller ID authentication information in determining how to deliver calls must publish a single point of contact on its public-facing website for call blocking error complaints. in context
• A terminating provider that blocks calls based on any analytics program, itself or through a third-party blocking service, must immediately return an appropriate response code to the call's origination point, and every voice service provider in the call path must transmit it. in context
• The 64.1200(k)(3) analytics safe harbor also requires that all analytics be applied in a non-discriminatory, competitively neutral manner. in context
• The terminating provider must resolve blocking disputes within a reasonable time and must at minimum give the disputing party a status update within 24 hours. in context
• Under 64.1200(n)(2), a gateway or originating provider that receives an FCC Enforcement Bureau Notice of Suspected Illegal Traffic must investigate and block or cease accepting the identified and substantially similar traffic on an ongoing basis. in context
• Under 47 CFR 64.1200(n)(1) a voice service provider must fully respond within 24 hours to a traceback request from the FCC, civil or criminal law enforcement, or the industry traceback consortium. in context
• The 64.1200(n)(1) 24-hour clock runs only in business hours (8 a.m. to 5:30 p.m.) on business days (Monday to Friday excluding Federal legal holidays). in context
• The national do-not-call safe harbor in 47 CFR 64.1200(c)(2)(i) requires using a version of the registry obtained from its administrator no more than 31 days before any call is made, along with written procedures and personnel training. in context
• 47 CFR 64.1200(a)(6) prohibits disconnecting an unanswered telemarketing call before at least 15 seconds or four rings. in context
• Under 47 CFR 64.1200(a)(7), a telemarketer may not abandon more than three percent of telemarketing calls answered live by a person, measured over a 30-day period for a single calling campaign. in context
• Under 47 CFR 64.1200(a)(7), a call is abandoned if it is not connected to a live sales representative within two seconds of the called person's completed greeting. in context
