[Freeswitch-users] Call State Diagram

Does a Call-State Diagram exist for FreeSwitch? I am looking for something similar to this: http://threebit.net/documentation/dialogic/resource.intel.com/telecom/suppor.... I have found a list of all the different states of a call ( http://wiki.freeswitch.org/wiki/Channel_States), but would like to see what events/actions trigger states changes to other states, etc. Thanks in advance, Guillermo Ruiz Camauer
