asterisk users - Jul 2013 - Send event/notification from one channel driver ot another

?
Is there a way to send an event notification from one Channel Driver to another
Channel Driver??If I wanted to have one channel driver do something custom
depending on the call state of the other channel driver?involved in the call,
how could you send some kind of event or state notification directly to this
other channel driver?
?
Thanks

Yes, although in general this happens within the Asterisk code itself and
is not exposed to the dialplan.

Typically, if anything (channel driver, resource module, etc.) wants to
notify a channel that something has occurred, it queues a control frame on
that channel. Control frames include things like media source changes/media
updates, indications that signalling actions should take place, etc.

What specific use case are you looking at?
