    Call pickup broken for DAHDI channels when beginning with #
    
    The call pickup feature did not work on DAHDI devices for anything other than
    feature codes beginning with * since all feature codes in chan_dahdi were
    originally hard-coded to begin with *.  This patch is also applied to
    chan_dahdi.c to fix this bug with radio modes.
    
    (closes issue AST-621)
