Hi,

I’m new to FreeSwitch world. I’m looking at using the mod_event_socket interface to write some simple call control app. The Events I’m interested at are CHANNEL_STATE and CHANNEL_CALLSTATE to recognize the status of the calls and how they progress. I have not found any docs describing the state machines for channels and Calls. I look up in the Source code as well and couldn’t find the place where the state machine is implemented.

Does anybody know where can I find this info?

EG, when setting up some call through FS these are the events I am getting with the uuids associated:
