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 60.
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 by means of the
Callƒforwarding
menu (see
the section entitled
MenuCard “Call Forwarding“
starting on
page 81).
Call Duration
All door calls are automatically terminated after a specific
period has expired. This ensures that forwarded door calls do
not unintentionally lead to continuous calls (e.g. to a mailbox).
Your system administrator can configure the period in the
Comfort Pro S/T-Comfort 930 DSL from 30 to 300 seconds and
will be able to tell you the current value.
