* From: Dr Scofield <hud@zurich.ibm.com>

* This patch removes voice code into a region module.  This required the implementation of events and other code to allow region modules to register their own caps handlers, and should allow different voice module implementations.
* CAVEAT: This does not provide complete voice support, it merely provides the hooks so that it can be plugged in.
