Forwarding Calls
17
Note: If you are the last reachable member of the hunt
group and you log out then any further callers will hear a
busy signal.
On a SIP terminal you cannot use the code-number procedure described here for
logging into or out of hunt groups. You can, however, operate this feature with the
OpenCTI 50 additional programme. To do so, the system administrator has to
authorise you to use this programme. For more information, please refer to the
online help of the OpenCom 100 / Aastra 800.
6. Forwarding Calls
Types of forwarding
You can forward internal or external calls intended for yourself to another
(internal or external) call number. Call forwardings can also be made to speed
dialling numbers which have been stored in the central telephone book (please
refer to the section Speed Dialling on page 6). You can decide whether only
internal, only external or both types of calls are forwarded.
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
(“Immediately”, “After Delay” or “On Busy”). However, only one forwarding
function can be activated for each mode.
Example:
You can configure “Immediate forwarding of external calls” to the number 333,
and “After Delay forwarding of internal calls” to the number 444.
On ISDN telephones, “Immediately”, “After Delay” and “On Busy” call forwarding
can also be set by means of a menu for all calls, i.e. internal and external.
Call forwarding is executed in the OpenCom 100 / Aastra 800, or in the case of
external calls, in the network operator’s exchange.
If your system administrator has given you the authorisation, then you can also
program call forwarding for call numbers of other users.
Call forwarding to a voicebox
If OpenVoice, the integrated voice-mail system of OpenCom 100 / Aastra 800, has
been installed, calls can also be forwarded to a voicebox which has been con-
figured for you.
