Patent ID: 7539502

Claim:
A method of operating an inter-carrier vendor having an assigned E.164 address and that is configured to route messages using SS7 signaling using the assigned E.164 address, the method comprising the steps of: at an inter-carrier vendor, receiving from a domestic carrier an E.164 address to be used as a “from” SCCP-level address instead of a static E.164 address assigned to the inter-carrier vendor; providing the received E.164 address to an inter-network network so that the received E.164 address is thereafter associated with the inter-carrier vendor; associating the received E.164 address with the domestic carrier within the inter-carrier vendor; and for subsequent outgoing SS7 messages being routed on behalf of the domestic carrier, replacing the static E.164 address with the received E.164 address as the “from” SCCP-level address.
