SYSTEM AND METHOD OF PROVIDING LOCAL NUMBER PORTABILITY

摘要

A system for and method of providing local number portability is presented. A request may be received to establish a session between an origination user agent and a destination user agent. The request may comprise a destination user agent identifier. It may be determined whether the destination user agent identifier was ported from one service provider to another. If so, routing information may be provided for establishing the session through the second service provider rather than through the first service provider. The session may be established over one or more Internet protocol networks.
