2.5.4 Answering a Callback
A callback request is executed when the other subscriber is free again. When you
hear the signal on your telephone, you…
H lift the handset, and the other subscriber will be called.
2.5.5 Forwarding Calls
Types of forwarding
You can forward internal or external calls intended for yourself to another internal
call number or, provided that you have the necessary user group authorisation, to
another external call number. Calls can be forwarded either immediately, after a
specified period of time (delay) or if the line is busy. You can configure more than
one call forwarding mode at the same time (
Immediately
,
Afterƒdelay
or
Busy
). You can, for example, configure call forwarding
Immediately
for external
calls to one call number, and call forwarding
Afterƒdelay
for internal calls to a
different call number. During configuration, the system administrator defines an
interval in seconds for
Afterƒdelay
call forwarding. You can replace this default
with your own individual value when programming
Afterƒdelay
call for-
warding. If more than one forwarding mode has been activated,
Immediately
is
given priority.
Call forwarding to a voicebox
If OpenVoice , the integrated voicemail system, is installed in the communications
system, 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 appli-
cation in the OpenCom 100 / Aastra 800 correspondingly. Ask your administrator
for the configuration applicable to you.
