ABSTRACT:
A method of providing number portability for the treatment of calls from a calling party to a specific number of a called party is disclosed. An Initial Address Message (IAM) containing the calling and called party's numbers to enable said call to reach said terminating office is forwarded from an originating office to a terminating office. Once the IAM is received at the terminating office, a determination of whether the call is directed to a portable number is made. If the call is directed to a portable number, a release message containing an indication that the called party number is a portable number and containing new routing information is forwarded from the terminating office to the originating office. A new IAM is then sent from the originating office to a terminating office associated with the routing information.
