TT#50013 fix message envelope playback

* envelope playback was disabled in the options,
      now reenabled back.
    * fix an issue when DTMF delay causing entering a
      suboption "advanced_options" straight away,
      e.g.: pressing '3' from the message playback
      entered "advanced_options" + immediately started
      with the menu item '3'. Now the options for
      "advanced options" are played correctly.
