Abstract
Methods, systems, and computer program products for using an LRN based query and response mechanism (e.g., a switching office number portability processing system) to route calls to IP multimedia subsystem (IMS) subscribers are disclosed. According to one method, an LRN based response message including a communications service subscriber identifier is received. An IMS gateway LRN associated with the communications service subscriber identifier may be determined. The IMS gateway LRN associated with the communications service subscriber identifier may be inserted into the LRN based response message and routing the message.
