The FTC published proposed amendments to the Pay-per-call Rule, including provisions to combat telephone bill "cramming" - inserting unauthorized charges on consumers' phone bills - and other abuses in the sale of products and services that are billed to the telephone, including voicemail, 900-number services, and other telephone-based information and entertainment services. A Federal Register Notice of October 30, 1998 solicited comments on the proposed Rule amendments, and invited commenters to apply to participate in a workshop forum. The workshop provided participants and the public the opportunity to discuss the issues, including the use of 800 and other toll-free numbers to offer pay-per-call services, the scope of the Rule, the dispute resolution process, and the need for obtaining authorization from consumers prior to charging their telephone bills. Participants included consumer groups, local and long-distance telephone companies, state law enforcement and regulatory agencies, pay-per-call providers, and associations representing broad interests ranging from service providers to billers of non-telecommunications services on telephone bills. There was an opportunity for members of the public to make oral presentations on both afternoons, following the conclusion of the discussion by participants of the agenda items.
