I wasn't sure if you were using those or not.  To be honest, the per-config attrs below were added precisely so we could disable all of them.  We're using the cookbook to build and manage the asterisk software, but aren't using any of the config files from the cookbook.  It's too hard to cover every use case for asterisk, even with LWRPs.  We've really embraced the 'application' vs 'library' cookbook approach for asterisk.
