The current technology advancements have enabled Telephony system manufactures to Integrate IP with existing telephony networks and offer converged solution for more optimum utilization of organization's IT infrastructure as well as internet bandwidth. The paper proposes an analytical method for determining basic traffic characteristics of systems servicing multi-rate overflow traffic streams generated by a finite number of sources. In particular, we describe an optimum solution for the implementation of telephony system. Analytical results of blocking probability calculated using the presented methodology has been compared with the data obtained from the system simulation process.
