Each intercom has its own "route" to the service center. For example, before you intercom "factorial".

Then dial "180180", then click "call", then dial "4" and again press the button "call".

If you entered the master code was wrong, the signal, which will publish the intercom is two-tone.
Alternately dial other number combinations: "9999", "6767", "12345", "3535", "11639" and "0000" (one of the combinations are just perfect).
