Call Forwarding

Telephony
Attributes
A call forwarding chain can contain any call forwarding types and call
forwarding users. There is no limit to the number of successive call forwarding
instances.
If the call forwarding destination is a system telephone, an incoming call is
additionally indicated with the display
via...
. The caller list of a system
telephone can also determine both the call number of the caller as well as the
call number of the user doing the forwarding.
In the case of multiple forwarding, a setting in the user group of the call
forwarding destination determines which of the “Via” call numbers is
displayed. You can have either the last call forwarding user (default) displayed
or the first call forwarding user in a chain displayed. The “Via” call number is,
however, only displayed when the call number display is activated for the
forwarding user.
Note:
When call forwarding to the Forum Voicemail voicebox
programme, the “Via” call number is evaluated in order to
determine the owner of a voicebox. The last call forwarding user
is used no matter what the user group setting. When call
forwarding using the secretarial function of the voicebox
programme, the call number of the voicebox owner is also
shown as the “Via” call number.
Loop Detection
Loops can generally occur during a call forwarding chain, e. g. when the call
forwarding destination refers back to the call forwarding source. This is why a
forwarded call has a call forwarding history. When the next call forwarding
destination is already included in the call forwarding history, a loop is detected
and any further call forwarding is prevented. If no parallel call signalling takes
