Author: anthm Date: Tue Feb 3 11:17:31 2009 New Revision: 11610 Log: Modify state machine behaviour. Endpoint handlers can still veto all other state handlers by returning SWITCH_STATUS_FALSE Application handlers can only veto each other by returning SWITCH_STATUS_FALSE. Global handlers will still be called when application vetos but they can still veto each other. Default handler will not be called if application or global vetos or if state has changed from any handler.
