  1. SIP Extensions for Caller Identity and Privacy<draft-ietf-sip-privacy-01.txt> Flemming Andreasen (fandreas@cisco.com) W. Marshall, K. K. Ramakrishnan, E. Miller, G. Russell, B. Beser, M. Mannette, K. Steinbrenner, D. Oran, F. Andreasen, J. Pickens, P. Lalwaney, J. Fellows, D. Evans, K. Kelly, M. Watson IETF - March 2001

  2. I-D Status • At the last IETF: • To date, very few comments received • No known issues • But “hum” did not reach consensus for WG Last Call • Since last IETF • Got one set of comments from Mark Watson • List discussion followed by list consensus on next steps • I-D updated accordingly

  3. The Comments • Generalize Remote-Party-ID • Make usable for any type of identity information • Define basic ones and incl. extension mechanism • Suggested five specific enhancements: • Requlatory Requirements • Types of Party • Types of Identity • Handling of Privacy Requirements • Location Information

  4. The Comments, cont. • Requlatory requirements • Both user and “network” must be able to request privacy. • Types of Party • Calling, called, connected, etc. • Types of Identity • Subscriber, user, terminal, etc. • Handling of privacy requirements • Each type may have its own requirement.

  5. The Comments, cont. • Location Information • Physical location of party, e.g. for E911 • Fair amount of list discussion led to consensus on: • Generalize Remote-Party-ID as suggested. • Include support for first four enhancements: • Requlatory requirements • Types of Party • Types of Identity • Handling of Privacy Requirements

  6. The Comments, cont. • Location Information was controversial though. • However • Location information not required for all applications. • A URL-based location information scheme could be supported as an extension. • Consensus on leaving out the specifics of location information from the draft.

  7. Spec Changes • Rpi-token (in Remote-Party-ID) • Removed rpi-type • Added rpi-pty-type, rpi-id-type, and rpi-privacy • Anonymity • Removed “full”, “uri”, and “name” • Updated processing rules incl. default handling of unknown Remote-Party-ID’s: • Must be marked as “non-screened” • Privacy must be afforded if requested.
