From 042cd57e948f6e3695d1d5b2b2a473ee77a1e9c4 Mon Sep 17 00:00:00 2001

Subject: * 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.
