    DTMF transfer plays the wrong sounds for wrong number or other call failure.
    
    * Set the default for features.conf.sample xferfailsound option to "beeperr"
    as documented instead of "pbx-invalid" and corrected the use of it in DTMF
    blind transfer (#1).
    
    * Improved DTMF blind transfer handling of wrong numbers.
    
    Most of the concerns in this issue were taken care of by the patch for
    issue 17999: Issues with DTMF triggered attended transfers.
    
    (closes issue #18379)
    Reported by: gincantalupo
    Tested by: rmudgett
