There is disclosed, for use in a wireless network, a call control processor containing finite state machines that are capable of communicating with one another and exchanging events, without requiring intervention by the operating system. The call control processor comprises a first state machine capable of performing a call processing task. The first state machine has an internal queue capable of storing events associated with the call processing task, where each event causes the first state machine to perform a selected action. The first state machine is capable of communicating with a second state machine of the call control processor by storing events directly into the internal queue associated with the second state machine. The second state machine subsequently executes the events stored in its internal queue.
