Hellmuth Michaelis 866a3fa2bf add support properly displaying and logging incoming telephone numbers (MSNs) 
by looking at the "type of number" field and providing configurable hooks
to correct the numbers accordingly. See keywords add-prefix, prefix-national
and prefix-international in isdnd.rc(5).
This feature was implemented by Christian Ullrich <chris@chrullrich.de>
