  Do not assume that the bridge_cdr is still attached to the channel when the 'h' exten is finished executing.
  
  It is possible for a masquerade operation to occur when the 'h' exten is operating. This operation moves
  the CDR records around causing the bridge_cdr to no longer exist on the channel where it is expected to.
  We can not safely modify it afterwards because of this, so don't even try.
