Private branch exchanges offer an ever increasing number of features which are traditionally implemented on an embedded processor within the PBX. With the advent of computer telephone integration they now offer methods to communicate with the outside world and let certain features be implemented on external workstations. In this paper we describe how Jini can be used to make legacy PBXs ready for the service age. We use least cost routing as an example service and describe an architecture which allows dynamically exchanging least cost routing data and logic while the PBX keeps running. We also present the experiences gained during implementation and trials.
