Abstract
Equipment providing information services, whether installed near a central office or provided as part of a PBX includes a search service for generating a number of outdialing operations in an effort to reach a subscriber of the search service for a caller. A plurality of outdialing operations are initiated simultaneously, sequentially, or as sets of calls in a sequence with each set including one or more simultaneously dialed telephone numbers. The numbers called may be extensions on a PBX, phone numbers within any area code, cellular phones, or any other type of number which can be reached by telephone. The caller is kept informed of the success or failure of the outdialing operations and when the subscriber called by the caller is reached, the two are connected and any other outdialing operation is terminated. When all of the outdialing operations for one set of telephone numbers is unsuccessful, the next set in sequence is used in one or more new outdialing operations.
