Matrix PRASAR UCS System Manual 379
When Service Provider-based LCR is programmed, whenever a number is dialed out, the system ignores
the area code, checks the number in the 'Service Provider-based LCR table', and routes the call according
to the trunk programmed for that number.
PRASAR UCS also supports LCR based on Carrier Pre-Selection. This type of LCR is useful where there
exist different service providers for local and long distance calls. Refer the topic “Least Cost Routing-
Carrier Pre-Selection” to know more.
Cost Factor
For LCR to work, all trunks that are allotted to extensions for making outgoing calls, must first be assigned a Cost
Factor.
Cost Factor is a number assigned to each trunk for identification. This number also serves as a preference number
for the trunk. The Cost Factor can be from 1 to 99. Trunks having the same preference must be assigned the same
Cost Factor. Different trunk types can also be assigned the same Cost Factor. These trunks are used for routing
calls.
By default all trunks are assigned Cost Factor number 01.
After assigning Cost Factor to Trunks, you must configure the Type of LCR to be used on Trunks in the Outgoing
Trunk Bundle Group (OGTBG) allotted to the extensions for making calls.
Assigning Cost Factor to Trunks
• On a sheet of paper, make a list of all the trunks assigned to extensions for making outgoing calls.
• Make a table of the trunk types and assign a cost factor to each trunk type, as shown below.
Program the Cost Factor number you assigned to the Trunk in the SIP trunk parameters. For instance, assign Cost
Factor 01 to SIP Trunk-01 and Cost Factor 002 to SIP Trunk-002.and so on.
Configuring Time-based LCR
• You can configure Time-based LCR for as many as 8 different Time Zones.
• On a sheet of paper, make a table for Time-based LCR.
