Signal During a Call
G
If the doorbell signal is triggered during a call, you hear a call
waiting tone. Proceed as described in the chapter
Doorbell, Door
Opener
, section
Signal During a Call
starting on page 66.
Door Call Forwarding
You can forward calls signalled from the doorbell to another (inter-
nal or external) call number, a so-called “pharmacy line”. This is
done by means of the
Callƒforwarding
menu (see the section
entitled
MenuCard “Call Forwarding”
starting on page 88).
Call Duration
All door calls are automatically terminated after a specific period
has expired. This ensures that forwarded door calls do not unin-
tentionally lead to continuous calls (e.g. to a mailbox).
Your system administrator can configure the period in the
Forum 500 / Forum 5000 from 30 to 300 seconds and will be able
to tell you the current value.
