Makes perfect sense.

Is the the correct way to add that data?

sub add_escalation_group {
  my $self = shift;
  my($id, $timeout) = @_;

  # 
  # create a new hash for this
  # data
  #
  my $h = { 'id' => $id, 'timeout' => $timeout, };

  #
  # add it to arrat
  #
  push @{$self->{'escalationgroups'}}, $h;

}
