Detailed Description

Test AMI hook.

Author

David Brooks dbroo.nosp@m.ks@d.nosp@m.igium.nosp@m..com based off of code written by Russell Bryant russe.nosp@m.ll@d.nosp@m.igium.nosp@m..com

This started, and continues to serves, as an example illustrating the ability for a custom module to hook into AMI. Registration for AMI events and sending of AMI actions is shown. A test has also been created that utilizes the original example in order to make sure the ami event hook gets raised.
