  1. BINDing URIs to SIP AORs Henning Schulzrinne Columbia University

  2. Summary • Information and actions associated with AOR: • scripts and call processing logic • conference control (floor control, conference management) via non-SIP protocols • upload presence • user provisioning • binding: SIP AOR  set of URIs • different degrees of indirection: • data URI • mid/cid URI • http, acap, ldap, ... URIs

  3. Binding vs. content indirection • Same: non-SIP URI references external data • content indirection: replace data carried in SIP body • binding: associate data with AOR

  4. Binding header field • Binding header field updates binding for particular purpose Binding: <http://www.tweak-me.com> ;disposition=configuration ;expires=0 ;q=0.1 Binding: <tftp://store.example.com> ;disposition=boot ;expires=36000 Binding: ;disposition=conference ;expires=0 • May be returned in by REGISTER, OPTIONS

  5. BIND method • REGISTER not appropriate to maintain bindings  multiple failure reasons, refresh intervals • Almost like REGISTER, but: • address to SIP URI  use methods parameter to direct to particular entity • handle both AOR and per-SIP URI bindings • ;expires=0  Delete all bindings for one disposition or individual URI • event package for updates

  6. Open issues • Is this useful in general? • For the applications envisioned? • Alternative: generalized PUBLISH • Details: • Status code "Maximum number of bindings exceeded"? • Tagged bindings for replacement?
