  10. Interworking using TIPHON • All existing call setup protocols use similar approaches • These are consistent with the TIPHON architecture • The TIPHON architecture flows are an excellent vehicle for interworking • H.323 • SIP • BICC Richard Brennan, Chair WG 3, ETSI Project TIPHON

  13. What we have done Richard Brennan, Chair WG 3, ETSI Project TIPHON

  14. Open Settlement Protocol • OSP Overview • TS 101 321 v2.1.1 • Communication Protocols • Hypertext Transfer Protocol (HTTP 1.1) • Secure Sockets Layer (SSL) Security • Message Format • Multipurpose Internet Mail Extensions (MIME) • Extended Markup Language (XML) Richard Brennan, Chair WG 3, ETSI Project TIPHON

  15. Typical OSP Architecture Clearing House OSP OSP Service Control Signaling Service Control Tiphon Zone H.323 Media Media Gateway Media Gateway Terminal Terminal Richard Brennan, Chair WG 3, ETSI Project TIPHON

  16. ETSI-TIPHON documents • ETSI DocBox • Open, Public access to draft deliverables http://docbox.etsi.org/tech-org/tiphon/document/tiphon Note: Hyperlinks on the following page are active in “Slide Show” mode! Richard Brennan, Chair WG 3, ETSI Project TIPHON
