      Datacalls with B410P fail.

      Incoming and outgoing call legs of a data call are using different
      formats: a-law, u-law.  When the call is bridged, the media stream is run
      through translation to convert the media formats.  The translation is bad
      for data calls.

      * Make incoming call that does not explicitly specify u-law or a-law use
      the DAHDI channel's default law.  The outgoing call always uses the
      default law from the DAHDI channel.

      (closes issue ABE-2800)
