    Made ISDN not add numbering plan prefix strings to empty numbers.
    
    When the Caller-ID is restricted, the expected behavior is for the
    Caller-ID to be blank.  In chan_dahdi, the national prefix is placed onto
    the Caller-ID number even if it is restricted (empty) causing the
    Caller-ID to be the national prefix rather than blank.
    
    This behavior was lost when sig_pri was extracted from chan_dahdi.
    
    * Made not add prefix strings to empty connected line, calling, and ANI
    number strings.
