Abstract
A system for conveniently extending the capabilities of network systems to support telephony is presented. Also, a method and system for preventing message looping within network devices that support telephony is presented. A network system, such as a proxy server, executes one or more executable service modules having instructions for performing a specific telephony service. A dispatcher operating upon the network device dispatches messages to the service modules according to a set of resource data provided by the service modules. To prevent message looping, the dispatcher executes logical instructions that restrict the service modules from routing messages to each other indefinitely.
