Standard Phone Rings Back after Intercom Call with
No One at Other End
Possible Cause 1: The switchhook is accidentally pressed and released, causing
a call to ring back.
What to do: Be sure that the handset is always replaced carefully. If the problem is
not solved, go to Possible Cause 2.
Possible Cause 2: Automatic Line Selection is programmed incorrectly.
What to do: If one of the phones involved is a standard single-line rotary or
touch-tone telephone, set its Automatic Line Selection to intercom first. If the
problem is not solved, call the hotline.*
