  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)
