Service providers, enterprises, and others who operate networks that use SIP (see [RFC3261]) need the ability to debug problems reported by end users and also to run regression tests if SIP client software/ hardware is upgraded. Such debugging and testing might be confined to a single service provider or network, or they may occur between the administrative domains of different network operators, including domains in different countries that are interconnected through networks belonging to one or more third parties.

Requirements for Marking SIP Messages to be Logged
SIP networks use signaling monitoring tools to debug customer- reported problems and for regression testing if network or client software is upgraded. As networks grow and become interconnected, including connection via transit networks, it becomes impractical to predict the path that SIP signaling will take between clients and, therefore, impractical to monitor SIP signaling end-to-end.
This document describes the requirements for adding an indicator to the SIP Protocol Data Unit (PDU) or a SIP message that marks the PDU as a candidate for logging. Such a marking will typically be applied as part of network testing controlled by the network operator and not used in regular client signaling. However, such a marking can be carried end-to-end, including the SIP terminals, even if a session originates and terminates in different networks.
