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. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Does anybody know where can I find this info?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>EG, when setting up some call through FS these are the events I am getting with the uuids associated:<o:p></o:p></p><p class=MsoNormal>bbac39e0-9025-4969-a6ba-b49c89b12237 CHANNEL_STATE CS_INIT<o:p></o:p></p><p class=MsoNormal>bbac39e0-9025-4969-a6ba-b49c89b12237 CHANNEL_CALLSTATE RINGING<o:p></o:p></p><p class=MsoNormal>bbac39e0-9025-4969-a6ba-b49c89b12237 CHANNEL_STATE CS_ROUTING<o:p></o:p></p><p class=MsoNormal>bbac39e0-9025-4969-a6ba-b49c89b12237 CHANNEL_STATE CS_CONSUME_MEDIA<o:p></o:p></p><p class=MsoNormal>9a66eaf9-e11e-4f9c-9623-19deac73fc2e CHANNEL_CALLSTATE ACTIVE<o:p></o:p></p><p class=MsoNormal>bbac39e0-9025-4969-a6ba-b49c89b12237 CHANNEL_CALLSTATE EARLY<o:p></o:p></p><p class=MsoNormal>bbac39e0-9025-4969-a6ba-b49c89b12237 CHANNEL_CALLSTATE ACTIVE<o:p></o:p></p><p class=MsoNormal>bbac39e0-9025-4969-a6ba-b49c89b12237 CHANNEL_STATE CS_EXECUTE<o:p></o:p></p><p class=MsoNormal>bbac39e0-9025-4969-a6ba-b49c89b12237 CHANNEL_STATE CS_HIBERNATE<o:p></o:p></p><p class=MsoNormal>9a66eaf9-e11e-4f9c-9623-19deac73fc2e CHANNEL_STATE CS_HIBERNATE<o:p></o:p></p><p class=MsoNormal>bbac39e0-9025-4969-a6ba-b49c89b12237 CHANNEL_STATE CS_RESET<o:p></o:p></p><p class=MsoNormal>9a66eaf9-e11e-4f9c-9623-19deac73fc2e CHANNEL_STATE CS_RESET<o:p></o:p></p><p class=MsoNormal>9a66eaf9-e11e-4f9c-9623-19deac73fc2e CHANNEL_STATE CS_SOFT_EXECUTE<o:p></o:p></p><p class=MsoNormal>bbac39e0-9025-4969-a6ba-b49c89b12237 CHANNEL_STATE CS_SOFT_EXECUTE<o:p></o:p></p><p class=MsoNormal>bbac39e0-9025-4969-a6ba-b49c89b12237 CHANNEL_STATE CS_CONSUME_MEDIA<o:p></o:p></p><p class=MsoNormal>bbac39e0-9025-4969-a6ba-b49c89b12237 CHANNEL_STATE CS_EXCHANGE_MEDIA<o:p></o:p></p><p class=MsoNormal>bbac39e0-9025-4969-a6ba-b49c89b12237 CHANNEL_CALLSTATE HANGUP<o:p></o:p></p><p class=MsoNormal>bbac39e0-9025-4969-a6ba-b49c89b12237 CHANNEL_STATE CS_HANGUP<o:p></o:p></p><p class=MsoNormal>9a66eaf9-e11e-4f9c-9623-19deac73fc2e CHANNEL_STATE CS_PARK<o:p></o:p></p><p class=MsoNormal>bbac39e0-9025-4969-a6ba-b49c89b12237 CHANNEL_STATE CS_REPORTING<o:p></o:p></p><p class=MsoNormal>bbac39e0-9025-4969-a6ba-b49c89b12237 CHANNEL_CALLSTATE DOWN<o:p></o:p></p><p class=MsoNormal>bbac39e0-9025-4969-a6ba-b49c89b12237 CHANNEL_STATE CS_DESTROY<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks in advance. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>David<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
