Abstract
Techniques are disclosed for verifying a caller ID field of an outbound telephone call. A termination service provider call server receives a call request from a calling endpoint. The call request includes a called endpoint telephone number, and a caller ID telephone number. The call request is forwarded to an inbound carrier call server servicing the called endpoint telephone number where it determines the termination service provider for the caller ID telephone number and sends a query back to the determined termination service provider to determine whether the caller ID telephone number is currently in use. The query includes the caller ID telephone number. The termination service provider call server determines whether the caller ID telephone number in the received query is currently in use. If the caller ID telephone number is not currently in use, it returns a fail message to the inbound carrier call server. If the caller ID telephone number is currently in use, it returns a pass message to the inbound carrier call server only if the caller ID telephone number has been currently in use for less than a predetermined time.
