INTERO - InterOperability Mechanisms for IN/IP Telephony

CTRIP draft specification

CTRIP is based on the Telephony Routing over IP (TRIP) protocol (RFC 3219), and the protocol is similar to TRIP with a new set of attributes. Currently, the draft specification only defines the attributes. It replaces Section 5 of RFC 3219 with a new Section 5 defining the attributes specific to CTRIP.

CTRIP defines more general versions of the corresponding concepts in TRIP. The most important modifications are the following:
 

ITAD (Internet Telephony Administrative Domain)	TAD (Telephony Administrative Domain)
Next hop server	Next hop address
LS (Location Server)	CTRIP-speaker
TRIP identifier	CTRIP identifier

For a complete description of the development of the CTRIP-protocol and the numbering architecture, please see the document "Nicklas Beijar: Distribution of Numbering Information in Interconnected Circuit and Packet Switched Networks" (PDF).
