  The ISDN CPE side should not exclusively pick B channels normally.
  
  Before this patch, Asterisk unconditionally picked B channels exclusively
  on the CPE side and normally allowed alternative B channels on the network
  side.  Now Asterisk does the opposite.
  
  Reasons for the CPE side to normally not pick B channels exclusively:
  *  For CPE point-to-multipoint mode (i.e. phone side), the CPE side does
  not have enough information to exclusively pick B channels.  (There may be
  other devices on the line.)
  *  Q.931 gives preference to the network side picking B channels.
  *  Some telcos require the CPE side to not pick B channels exclusively.
  
  (closes issue #14383)
