Title Design and implementation of a software module for the Media Server introduction in a Java
Call Control development environment.
Supervisor Prof. Gianluca Reali
Abstract The purpose of the thesis activity is the implementation of a software module for the
introduction of Media Server in a JCC development environment. JCC is the acronym for Java
Call Control and it represents a set of Java APIs for defining, developing and monitoring
telephony calls and services.
The proposed solution, developed using Java programming language, is a module easy to
integrate in a JCC Resource Adaptor and able to be installed in a JSLEE Application Server. The
software module allows to obtain typical Media Server functionalities using MGCP protocol.
The software module installed in a SIP-based JCC RA offers a powerful tool to create a
multimedia VoIP service in JCC development environment.
