+Note Upgrading Asterisk:
+
+After you cvs update (or make update) Asterisk you have to go into
+asterisk/channels/h323 and issue a make clean, before compiling the
+rest of asterisk. Doing this process every time you upgrade Asterisk
+will ensure a sane build.
+
+
+If you are still having trouble contact 'JerJer' in #Asterisk on 
+irc.freenode.net or send reasonable debug information to support@nufone.net.
