Telephoning
configuration, the system administrator defines an interval in seconds for After delay
call forwarding. You can replace this default with your own individual value when pro-
gramming After delay call forwarding. If more than one forwarding mode has been
activated, Immediately is given priority.
Call forwarding to a voicebox
If OpenVoice / Aastra Voice, the integrated voicemail system of the OpenCom 100 /
Aastra 800, is installed, you can also forward your calls to a voicebox configured for
you.
Selective Call Forwarding
Further, the system administrator can programme call forwarding where the call
number of the caller is analysed ("SCF: Selective Call Forwarding"). Potentially this
could be the reason why specific calls do not reach you. If you have any questions
concerning this functionality, please consult your system administrator.
Least Cost Routing
Least Cost Routing (LCR) can be evaluated with call forwarding to external numbers,
provided your system administrator has configured LCR and its application in the
OpenCom 100 / Aastra 800 correspondingly. Ask your administrator for the configu-
ration applicable to you.
Hunt group call numbers
During system configuration, the system administrator can configure call forwarding
destinations for hunt group call numbers. These destinations are called when all users
of a hunt group are busy and/or when a call is not accepted by any member of the
hunt group within a certain time interval. You cannot view or change this call for-
warding on your device.
In addition, the system administrator can determine whether you can forward
incoming calls to the hunt group call number or not. If the system administrator does
not permit call forwarding for your hunt group call number, any call forwarding that
you have programmed on your device is not carried out upon a hunt group call.
Call forwarding chains
The system administrator can configure the system so multiple call forwarding
instances can be linked one to another to form a chain. A simple example: user A for-
wards to user B, who then forwards to user C. A call for user A is then directly signalled
to user C.
A setting in your user group regulates which call number appears on your device
when a call which has been forwarded multiple times is signalled on your device: you
will see either the call number of the last user who programmed the last call for-
