Sec. 64.1512  Involuntary blocking of pay-per-call services.

    Nothing in this subpart shall preclude a common carrier or 
information provider from blocking or ordering the blocking of its 
interstate pay-per-call programs from numbers assigned to subscribers 
who have incurred, but not paid, legitimate pay-per-call charges, except 
that a subscriber who has filed a complaint regarding a particular pay-
per-call program pursuant to procedures established by the Federal Trade 
Commission under title III of the TDDRA shall not be involuntarily 
blocked from access to that program while such a complaint is pending. 
This restriction is not intended to preclude involuntary blocking when a 
carrier or IP has decided in one instance to sustain charges against a 
subscriber but that subscriber files additional separate complaints.
