Detailed Description
The response and properties of Call Deflection are similar to those of Call Forwarding
Unconditional.
Tab. 138 Call Deflection
Other properties:
• The internal number of a call distribution element can only be used as the destina-
tion for a Call Deflection in a special case, namely if at least one CDE destination is
configured on ACD. If not, Not available is displayed whenever the function is acti-
vated. Any configured CDE destinations that are not ACD are never executed.
• If the called user is busy and the calling user activates call waiting, the call can also
be forwarded. The response and the options available are the same as for a user
who is free.
• Calls on the line of a key telephone or an operator console cannot be forwarded (ex-
ception: the Personal key on an operator console).
• If the call is not answered at the destination, a recall is not made.
• If an attempt is made to forward the call to an invalid or busy internal call number,
the function is not executed and the ringing is signalled as before. By contrast Call
Deflection to an external user is always executed.

If caller A is an external user or a virtual network PISN user, the settings authorising exchange-to-exchange
traffic (see "Call Forwarding Unconditional to exchange", page 336
) will have to be observed. (If the connec-
tion is not authorized, the call is not forwarded.)
