Detailed Description
Tab. 153 Call Forwarding Unconditional
Note:
The internal number of a call distribution element can only be used as the
destination for a CFU in a special case, namely if at least one CDE destina-
tion is configured on ACD. If not,
Not available
is displayed whenever the
function is activated. Any configured CDE destinations that are not ACD
are never executed.
Call forwarding chains:
• Internal: CFU chains can be set up locally (maximum 20);
• In the PISN: CFU chains are permitted. They are however restricted by the transit
counter.
Note:
The function code *67 (CFB) and *61 (Call Forwarding on No Reply)
interrupts a chain of call forwarding (*67 or *61 is no longer carried
out).
Call forwarding loops:
• Internal: not permitted.
• In the PISN: restricted by the transit counter.
C is the only user who can still reach B.
