[Freeswitch-users] ESL for subscribing Channel Events

[Michael Jerris]

If you want to get those events just connect to ESL and subscribe to them.  Are you saying you want to have a connection per channel but include create events?  You would have a chicken and egg problem there but in that case what do you actually need the create event for, surely another event can be used instead.
