Call Compliance.com, Inc. released Teleblock, a service to help prevent telemarketers from erroneously completing outgoing calls to numbers on state and proprietary Do Not Call lists. Teleblock connects to telemarketers' phone lines and automatically blocks numbers dialed that appear on Do Not Call lists. The service does not require upgrades or modifications to existing telephone systems and is designed to help telemarketers attain compliance as painlessly as possible. As part of the service, CallCompliance automatically updates state Do Not Call lists as they become available from each jurisdiction. Telemarketers also can log on to their Web site and block additional numbers of individuals who make such requests to the company directly.
