In general, there is no explicit tying of events with a particular action
that caused those events, as AMI events are completely independent of AMI
actions.  The exception to this, of course, are AMI events that are reporting
success/failure of an AMI action, in which case they will share the same
ActionId header (if the action specified an ActionId as well).

In your particular case, if I were writing a system that wanted to associate
a created channel with an Originate Action, after I issue the Originate,
I'd listen for a NewChannel event.  If that NewChannel event specified a
channel that was created in the context I specified and with a
technology/extension that I specified, I'd set that as the channel I just
asked to be created. From there on, subsequent events (VarSet, NewExten,
Hangup, etc.) that are associated with that channel will contain a Channel:
header with that value.
