Release 4 contains GCCS and MPCCS. ‡ The specification is under “change control”: version 4.0.0. In Sep/Oct 3GPP plenary will likely approve final version 4.0.x Rel. 4, v. 4.0.x ~Oct 01~Mar 02 JCAT

6. Jain/Bakker – 6 Fun Facts About JCC  JCC 1.0 Reference Implementation (RI) and Test Compatibility Kit (TCK) are available for free download at Telcordia site: http://www.argreenhouse.com/JAINRefCode/  JCC 1.0 API (First Public Release) available at SUN site  JCC implementation discussion list: http://groups.yahoo.com/group/jainjcc  Telcordia AR Mini Call Agent prototype passes the TCK JCC is a simplified version of Parlay’s MPCCS. JCC aligns with JTAPI and Parlay MPCCS. JCC is protocol agnostic. JCC is out there and available!

8. Jain/Bakker – 8 JAIN JCAT Requirements  JCAT –A rich call model to address the concerns of the JAIN community and still have alignment with Parlay and JTAPI –Addresses end-office (Class 5, local exchange) environment –Explicitly models terminals unlike JCC and Parlay  Support first-party as well as third-party calls  JCAT Expert Group Spec Lead (Telcordia) is obligated to release: –API Specification document  Rigorously defined: Pre and post-conditions, FSM, use Java patterns –Reference Implementation (RI) –Test Compatibility Kit (TCK)

15. Jain/Bakker – 15 Conclusions  Open APIs are here!  Call Control APIs and network signaling protocols like SIP are complementary, not competing “The JAIN and Parlay sets of APIs are among the first to emerge that hold the promise of this simplified, collaborative development environment. … While these initiatives compete with each other in some respects, they are also complementary, with each API incorporating elements of the others. Most emerging vendors will support at least JAIN and Parlay …” - Yankee Group, 9/2000
