call key. You speak with the visitor.
Door call during call
If the doorbell signal is triggered during a call, you hear the call-waiting tone. Proceed as described under
Opening door during call starting on page 85.
Door call forwarding
You can forward calls signalled from the doorbell to another (internal or external) call number (a so-called
"pharmacy line"). This is done via the Call forwarding menu (see page 114).
Call duration
All door calls are automatically terminated after a specific time interval has expired (default is 60 seconds).
This ensures that forwarded door calls do not unintentionally lead to continuous calls (e.g. to a voicebox).
Your system administrator can configure the time interval in the Comfort Pro from 30 to 300 seconds and will
be able to tell you the current value.
