ABSTRACT:
Method and system are provided for efficient telephone number portability within a geographically dispersed telephony and the like switching system, wherein ported telephone numbers, when dialled and found non-existent at their number-inherent destination, a "Release Treatment" with a trigger (automatic flexible routing) searches in a database from the originating switching node or office, whereupon their new network node address is directly connected to following normal routing procedures; thus permitting realistically affordable telephone number portability, particularly local number portability (LNP).
