External call forwarding with a multi-
ple subscriber number
If your communication system is connected to an ISDN
multiple device line, then you can forward all incoming
calls from the public network through your multiple sub-
scriber number (MSN) to an external destination.
There are three types of forwarding:
•
Calls are forwarded immediately (1=immediate call
forwarding).
• Calls are forwarded after a certain time (2=unan-
swered calls).
• Calls are only forwarded when the line is busy
(3=when busy).
