S2-001437 from Siemens: CSCF Availability during the SIP Session
This document proposes to standardise the use of the optional SIP Record-Route mechanism to enable the CSCF or any proxy to stay within the SIP signalling path and so to keep control over the session until the session is released.
Discussion: It’s Ok to state that a mechanism is needed to ensure that a CSCF remains within the signalling path, but the proposed mechanism itself should be decided by CN, according to Lucent, BT and Motorola.
