Enhancing java call control with media server control functions

In this article, we propose a novel abstraction layer for application service implementation compliant with the Java Call Control (JCC) specifications. It simplifies creation of multimedia services using SIP and the Media Gateway Control Protocol. In order to show its effectiveness, we have implemented a JCC resource adaptor for a JAIN service logic execution environment (JSLEE), using the Mobicents application server, which is the only existing open source JSLEE implementation. Experimental results obtained by implementing a complex VoIP service show both a significant simplification of service implementation and improved performance over legacy solutions.
