The present invention affords a predefined class of authorized users of the PSTN (public switched telephone network) access to extended telephone services through public communication networks external to the PSTN, the latter networks including the web and Internet. Authorized users in the predefined class can receive the extended services at residences, offices, and locations remote from both residences and offices. Authorized users can activate respective extended services through the external networks, and can do so without having to communicate with telephone company representatives. Resource management intelligence of the PSTN is adapted to link to the external networks for communicating with and delivering extended telephone services to the authorized users. Extended telephone services include variations of presently standard telephone services such as call waiting, caller ID, call forwarding facsimile image transmittal, voice mail, etc. Presently contemplated adaptations of PSTN intelligence include adaptations allowing for the interception of analog telephone signals and the redirection of the intercepted signals in digital form through external data communication networks such as the web. A web user who is also in the class of authorized PSTN users can activate and receive delivery of extended telephone services at a computer linked to the PSTN intelligence through the web, regardless of how and where the connection to the web is made. Thus, the web user can receive the extended services through a telephone line associated with a base telephone account (e.g. a line in a respective residence or office), as well as through a line (telephone or other) separate from and/or remote from the associated telephone line.
