New Revision: 2262

Log:
Problems with ISDN MWI to phones.
1) The "controlling user number" is always the number of the voice mail box
which is identical with the subscriber number itself. This number which
is listed in the ISDN phone MWI menu cannot be called back to contact the
voice mail box. The controlling user number should be made configurable.
2) The MWI indication is not restricted to a user (broadcast facility with
dummy call reference). A called party IE should be added to address only
the relevant MSN. (ETSI 300-196 Section 8.3.2.4)
