Life of the channel. you have channel and pool in your session

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.
