This paper proposes to use a cluster of call servers for switching calls on a telecommunication switch. Using a call server cluster has a number of advantages that includes enhanced reliability and performance. When a call is generated, it is necessary to determine which call server in the cluster is to switch the call. In this paper we have introduced three call server selection strategies that are based on call characteristics. Using a simulation model the performance of these strategies is analyzed. A number of insights that capture the impact of system and workload parameters on performance is discussed.
