Agenda Enterprise Applications Traditional Telephony Apps OracleAS Solution Solution Architecture Architecture Benefits Click-to-Dial: Flow & Demo Other Flows (Call Center, Voic , PBX) A Case Study Conferencing App Flow Value Proposal of Architecture Summary

Enterprise Telephony Apps –Phone-accessed applications –Access enterprise back-ends –Have call control capabilities (make a call, auto-answer) Sample Apps –Call Centers / Customer Support –IVRs: Corporate Directory –Unified Messaging –Conferencing –IP PBX –Next-Gen Telephony Apps Click to Dial Notification Services Personal Assistant Johnny Wong – Oracle Corporation Enterprise Applications

Traditional Telephony Apps Problem Hardware-based deployment Dialogic Cards Expensive Hard to integrate with other sub-systems , LDAP server Requires very specialized knowledge Solution: Bring Development to Web Application Server Model Based on standard software and commodity hardware Easy to integrate with other systems Widespread web application development knowledge
