Hi, anyone knows where i can download the callback.rb?

As the freepbx callback got some problems indicated in,
http://www.aussievoip.com/wiki/freePBX-Callback

And i want to apply this ruby rule, however, the link for downloading is not available any more,

any one knows where i can download it again?

Both the API and the ruby version are both here.

And I just did testing on TB beta5

Out of the box both CALLBACK and DISA work perfect not one failure

The ruby version fails on TB
The cause maybe this error when installing on ruby on TB;
Note this error only happens on TB as far as I can tell (or if you have enabled the TB repo on another box).
