LEAST COST ROUTING
9.12.1
GENERAL
The Least Cost Routing Facility can be accessed by dialing Least Cost Routing Access
Code (LAC).
By using Least Cost Routing Access Code you will automatically be routed over the
cheapest available route. You cannot choose the cheapest route yourself, this is
performed automatically by LCR.

PROCEDURE

Outgoing call by using LAC
•
Lift hand set
•
Dial LAC provided a dial tone is received.
•
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.
•
Replace the handset when the call is completed.
9.13
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 calling party number, date,
time, and so on).
The following is the procedure for invoking malicious call tracing while connected to a
subscriber:
