SIP Torture Test Messages for IPv6 ● -03 fairly complete. ● Some pending comments will be folded into next revision after San Diego. ● One open issue around representing IPv6 literals in Via ;received parameter: use [ and ]? Or not? Via: SIP/2.0/TCP foo.example.com;received=[2001::db8];branch=... OR Via: SIP/2.0/TCP foo.example.com;received=2001::db8;branch=... ● At 18 th SIPit (April 2006), we observed: ● “Those testing IPv6 made different assumptions about enclosing literal v6 addresses in Vias in []. By the end of the event, most implementations were accepting either. Its about 50/50 on what gets sent.” – RjS.

SIP Torture Test Messages for IPv6 - Draft Update ● Currently: authors prefer using [ and ]. However, no consensus on the list. ● Therefore: Following the Robustness Principle of RFC1122, S3.4 of –03 contains two test cases; one using [ and ], and the other without. Implementations are expected to pass both.

draft-littlefield-sipping- mgmt-event-01 ● What? ● Defines a “Management Request” Event Package to trigger UA establishment of management sessions ● Why? ● Difficult to reach UAs behind NAT and Firewall devices for management ● Key Features ● UAs can indicate supported management protocols & SUBSCRIBE to a compatible Management System ● Allows Management System to NOTIFY client when a management session is needed
