8. 4. 1. 1 Call Forwarding Unconditional to exchange
Settings for exchange-to-exchange traffic (see also "Exchange access authoriza-
tions", page 315 )
• Exchange-to-exchange connection enabled:
– External and internal calls are diverted to an external destination; a first-ring
CFU is not carried out. Requirement: User with direct dial is defined.
– If the conditions for transferring the Call Forwarding Unconditional to the
exchange are also met, the connection is transferred to the network (see
"Transferring Call Forwarding Unconditional to the Exchange", page 206 ).
Note:
Exchange-to-exchange connections can be further restricted, see
"Exchange-to-Exchange Connection", page 199 .
• Exchange-to-exchange connection not enabled:
– External calls are not diverted to an external destination.
– Internal calls are diverted to an external destination.
Calls that reach the user via user group are diverted externally only if the parame-
ters on the user group and user allow it (
"Call Forwarding Unconditional (CFU) for
user group members", page 107 ).
8. 4. 1. 2 Wait for connection setting
Specifies whether a Call Forwarding Unconditional of an external call to the ex-
change is always switched through or only if the called party answers a call (and a
connection is therefore set up):
• Wait for connection = No
The Call Forwarding Unconditional is always switched through.
• Wait for connection = Yes
The Call Forwarding Unconditional is switched through only if a connection is
set up.
If the destination user is busy or unobtainable, this setting ensures that the caller
does not incur charges for the connection up to the PBX.
