It is easy to write a converged J2EE/HTTP/SIP application using WebLogic SIP Server. This article details the architecture behind a complete conferencing application using the Cantata media server for voice and video streaming.

The conferencing application detailed in the article took two savvy developers less than a month to complete, and it is now being reused in demonstrations, POCs and trials across BEA. It is the most comprehensive example to date of using the BEA technology suite (WebLogic SIP Server, WebLogic Workshop, XML Beans) to build a real telco application.

Now that WebLogic SIP Server 2.2 is out with Diameter support and with APIs that support true HTTP/SIP session sharing, BEA is in a great position to become a leading IMS server vendor.
