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 Opening the Door During a Call starting on
page 86.
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 through the
Call forwarding
menu (see the section
entitled
MenuCard “Call Forwarding”
starting on page 118).
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. Ask him what
the current time value is.
