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 90.
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 119).
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 Aastra 800 / OpenCom 100 from 30 to 300 seconds and will be
able to tell you the current value.
