PROCEDURE
Outgoing call Using LAC
1)
Lift the handset
2)
Dial LAC. If provided, a dial tone is received.
3)
Continue with the external number If no free trunk is selected a busy tone is
received. On-hook queuing is possible by dialing the suffix digit for call-back to
the busy route. If the selected route is marked as expensive you will receive
Expensive Route Warning Tone which will make it possible for you to interrupt
the further routing of the call.
4)
Replace the handset when the call is completed.
MALICIOUS CALL TRACING (MCT)
This feature allows you, before the call is disconnected, to signal to the public switched
telephone network (PSTN) that you have received a malicious call. If the calling
subscriber clears the call, the external line can be held for a limited period of time,
during which you can invoke the feature. This information is used by the PSTN to
record information about the origin of the call (that is, print out calling party number,
date, time and so on).
The system administrator must assign the MCT feature to a function key.
To order Malicious Call Tracing, press the MCT key:
•
If the request is successful, the lamp (LED) is lit, a text message is shown in the
display and an acknowledge tone is heard.
•
If the request fails, the lamp (LED) associated to the key flashes rapidly, a text
message is shown in the display and a reject tone is heard.
MULTIPLE TERMINAL SERVICE, TAKE OWN CALL ON
ANOTHER TERMINAL
A call in two-party speech can be taken/moved onto another terminal belonging to the
same user, by dialing a service code. If more than one terminal has a call in speech no
call will be picked.
If no call is picked, a further analysis is done to find if any other call can be picked (i.e.
common bell, group call or universal night service).
To enable this function, do the following
•
Dial *8# from the new terminal.
Note: Finland and Sweden, press *0#.
U.S. and Canada, press *59#.
NIGHT SERVICE
During night service, incoming external calls are transferred to any selected extension
or group of extensions.
