As the telecom and IT industries converge, pressure is mounting for convergence of service across the two domains, and future integrated services in the telecom domain are subject to specific requirements such as support for end-to-end communication sessions and mechanisms for service interaction across technological borders including telecom, enterprise, and Internet services. This paper provides an integrated services orchestration bus to handle the interoperation and compositions of services from the different domain and focus on the components lifecycle management, normalized message routing, normalized message parsing and mapping, events serialization processing, JNDI register management, and deploy unit. The multimedia conferencing-use case scenario is illustrated, and also the performance is measured and analyzed. Finally, we give the conclusions and future work.
