Abstract
A system and method for allocating an incoming call to a desired one of a plurality of destination candidates in response to data in at least one predetermined category concerning a caller, e.g. the area, the company or the department of the caller (a source address mode). There may be other modes such as a direct in line (DIL) mode and global mode. When a call is received by one of trunk circuits, the termination mode for the call is set for one associated with the trunk circuit that received the call. In case of the source address mode, the call is allocated to one of the destination candidates which is associated with the caller number or a part thereof. An association between a caller number (a part thereof) and a destination candidate is preferably achieved using a destination information table containing at least such information. In creating the table, designations of telephone or toll numbers of prospective callers are advantageously achieve by specifying data in at least one predetermined category concerning each caller.
