Channel variables are strings that can be set/get just about everywhere in FreeSWITCH. Often used in the dialplan to tweak behavior of a dialplan app. Private channel data is used by the module C code to store a pointer to some data that is referenced by a name. This data would exist in the scope of the channel that it is set on. One typical example is to store a media bug as private data so that it can be later removed from a session.

Hi all,
While trying to add some features to mod_conference I found two functions for access channel data:
* switch_channel_get_variable(channel, "conference_controls");
This one is clear, but also
* switch_channel_get_private(channel, "_conference_autocall_list_");
Can somebody clarify to me (and maybe to others) what is the purpose of this mechanism? What kind of channel data are generally manipulated this way? Are there useable/settable from application level (dialplan or scripts)?
Regards,
Mariusz
