Abstract

A system and method that overrides the initial destination number of an SMS message based on the destination number in the message itself. The communications device, a serving MSC or STP checks the destination address and overwrites the default SMSC address with a local special number service center address when it detects a special number destination address recognized anywhere in the world (e.g., 9-1-1, 1-1-2, 1-1-0, etc.). The message is then delivered to a local special number service center. The special number service center then delivers the message to an answering point, which then communicates with the caller.
