Telephony Routing over IP (TRIP)

TRIP (Telephony Routing over IP, RFC 3219) is a policy driven dynamic routing protocol for advertising the reachability of telephony destinations, and for advertising attributes of the routes to those destinations. TRIPs operation is independent of any signaling protocol, hence TRIP can serve as the telephony routing protocol for any signaling protocol.
