Call routing
179
System functions and features as of R4.1
syd-0570/1.2 – R4.1 – 08.2016
Other features of the default call forwarding function:
• Unlike CFNR (*61), for Default call forwarding if no answer the terminal forward-
ing the call does not carry on ringing in parallel.
• The Default Call Forwarding is not executed if no terminal is connected (Exception:
A user with only one analogue terminal). Instead the destinations configured for
when the user is unobtainable are applied (see "Response if unobtainable",
page 186).
• The delay timer for default call forwarding is restarted after each new connection at-
tempt.
Default Call Forwarding with calls already forwarded:
Situation: User A calls user B, who has redirected to user C. A default call forwarding
to user D is configured at user C.
Tab. 33 Default Call Forwarding response to calls already forwarded
Entry under CDE if no answer in the CDE con-
figuration
Depends on the times configured:
If the CDE call forwarding delay in the CDE configuration is
shorter than the external delay of the default call forwarding,
CDE call forwarding is activated; otherwise, default call for-
warding is performed.
Entry under CDE if busy in the CDE configura-
tion
The CDE call forwarding when busy always has priority over
the default call forwarding when busy.
User is unobtainable If for technical reasons a user is unobtainable, the destinations
configured for the user when the user is unobtainable are
applied (see "Response if unobtainable", page 186
).
Routing the call to the user via UG Default call forwarding is not implemented. (Exception: Default
call forwarding when busy is active and the user as well as all
UG members are busy.)
