1. A communication system comprising:
- a plurality of subscriber communication lines, each assigned a respective directory number; and
a switching system for providing selective communication connections between at least two of said subscriber communication lines, said switching system comprising a programmed controller for responding to initiation of a dialed call originated at one of said subscriber communication lines;
wherein said programmed controller comprises data storage for storing a call processing record for a predetermined directory number, said call processing record containing data related to selected ones of said communication lines; and
said programmed controller is responsive to a call dialed to said predetermined directory number by a calling party from one of said selected communication lines for which said data is contained in said call processing record to permit change and update of the data stored in said call processing record, and the privileges with which the call processing record may be changed by a calling party from one of '"'"'said selected ones of said communications lines are in said data.

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.

9. In a communication system including at least one switching system connected to a plurality of subscriber lines and connected through a signaling network to a database comprising at least one call processing record assigned to a predetermined directory number, said call processing record containing selected directory numbers, a method of call processing comprising the steps of:
-
determining that a call is dialed to said predetermined directory number; identifying the directory number of a calling subscriber line; comparing the directory number of the calling subscriber line with selected directory numbers in said call processing record; in response to a resulting non-match in the comparing step, completing the call in accordance with said call processing record; and in response to a matching result in the comparing step, permitting the changing of information contained in said call processing record. - View Dependent Claims (10, 11, 12, 13, 14)

15. In a switched telephone network system for completing calls to a plurality of subscriber lines with transmission of ringing signals, the subscriber lines assigned respective directory numbers, a method of call processing comprising the steps of:
-
routing a call dialed to a predetermined directory number to a selected subscriber line destination that is not assigned the predetermined directory number, said predetermined directory number is a virtual number associated with a plurality of destination directory numbers, one of which is associated with said selected subscriber line destination; transmitting a distinctive ringing signal to said destination that is different from the ringing signal transmitted in a call dialed to the directory number of the subscriber line destination; identifying the subscriber line that initiated the call; temporarily suspending the call; accessing a database for routing information; and switching the call for completion in accordance with the routing information, wherein said routing step further comprises the steps of comparing the directory number of the calling subscriber line with destination directory numbers in the database and completing the call if there is no match in the comparing step. - View Dependent Claims (16)

17. In a telephone communication system including at least one central office switching system connected to a plurality of subscriber lines each having an assigned directory number, a voice network portion comprising voice communication paths for interconnecting at least two of the subscriber lines, a common channel signaling network portion comprising signaling paths interconnecting said central office switching system through at least one signal transfer point and at least one integrated services control point including a data base, a method of call redirection processing with distinctive ringing on a per call basis comprising the steps of:
-
storing call redirection information in a call processing record in said data base for a predetermined directory number; setting a trigger at a switching service point for accessing said data base in response to a call dialed to said predetermined directory number from an originating subscriber line; in response to said trigger being activated, establishing a voice communication path between said originating subscriber line and a subscriber line destination having a directory number associated with the call processing record redirection information; and transmitting a distinctive ringing signal to the destination subscriber line that is different from the ringing signal transmitted in calls dialed to the destination subscriber line directory number. - View Dependent Claims (18, 19, 20, 21, 22, 23)
