ABSTRACT:
In a personal communication service (PCS) environment, where a call to a personal telephone number may be routed to a sequence of telephone numbers until the call is answered or abandoned, and where it is possible that the telephone number of the caller is one of the numbers in the sequence, the call to the personal telephone number is processed by a) determining if the automatic numbering identification (ANI), i.e., the telephone number, of the calling telephone is the same as a telephone number of the sequence, and, if so, b) skipping over that telephone number, i.e., the caller's telephone number, so that no attempt is made to complete a PCS call to the calling telephone.
