Life of the channel. you have channel and pool in your session
everywhere you go you use the session to malloc with
switch_core_session_alloc(session, <size>)
The endpoint module gets the first crack at implementing the state
if it wants to, it can cancel the default behavior by returning SWITCH_STATUS_FALSE
Next comes the channel's event handler table that can be set by an application
which also can veto the next behavior in line by returning SWITCH_STATUS_FALSE
Finally the default state behavior is called.
