Abstract

Telephone communications systems and methods are provided enabling subscribers to establish an easily changed plan for call completion, over an Advanced Intelligent Network to any of several alternative locations, of calls dialed to a single directory number. A call to the same directory number by an authorized caller can enable the caller immediately to update the call completion plan dependent on the caller's status. A distinctive ringing signal is applied on a per-call basis to calls completed under the call completion plan. The call completion plan is maintained as a part of a call processing record at an ISCP.
