4. 4 Tracking Progress http://www.softarmor.com/sipping/process/review_procedu re.html Tracking WG documents, including WG reviews, assignments and status, with proposed WGLC (and IESG) dates for all WG documents. Updated about every 4 weeks (3 updates since IETF-70) Important for doc editors to review deadlines and make sure current status of docs is accurate. WG reviews are cached in the spreadsheet Information is used by other SDOs to track dependencies. Overall progress since IETF-70 has been reasonable: Given the short timeframe and the holidays.

18. 18 Lightweight SIP Toolkit for P2P and Basic CS SIP (draft-sinnreich-sip-tools-02) Focus on Internet multimedia RT communications An alternative to SIP services in the network with app servers Applications reside in the endpoints, including complex call scenarios (I1)* SIP in the network is used only for rendezvous (location) and session setup Applicable to both Client Server (CS) and P2P SIP Tool set for implementations includes NAT traversal, security Reduces SIP specific RFCs as of early 2008 from roughly 100 to about 9-10 (I1)* More RFCs and informative I-D on NAT traversal and security *I1 is still informative I-D:draft-ietf-sipping-cc-framework. Will be RFC.
