Matrix NAVAN CNX200 System Manual 679
When Service Provider-based LCR is configured, 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 lowest cost trunk configured for that number.
NAVAN 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
“Least Cost Routing - Carrier Pre-
Selection” topic to know more.
Cost Factor
Cost Factor is used for grading the cost of routing calls from a trunk for the purpose of least cost routing. For LCR
to work, all trunks that are allotted to extensions for making outgoing calls, must first be assigned a Cost Factor,
starting from 01 to 99.
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 CO, Mobile and SIP
Trunks.
Assigning Cost Factor to Trunks
To assign Cost Factor to the trunks,
• Click Least Cost Routing (LCR) .
• Click the Cost Factor link. This page displays the Cost Factor table.
• The Cost Factor table displays all the Port Type-Number of the system and the Trunk Names.
• In Cost Factor column of the table, assign a cost factor to each trunk type. For instance, assign Cost
Factor 01 to CO1 and Cost Factor 02 to CO2. Similarly, assign Cost Factor 03 to Mobile Trunk 1, Cost
factor 04 to Mobile Trunk 2, Cost Factor 05 to SIP trunk 1.
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.
• Define the Time Zone, i.e. the start and end time, when the LCR should be applied for the outgoing calls.
• For each Time Zone that you define, select the Trunk with the lowest cost as your first preference, i.e.
Preference 1. Select the trunk of your second, third and fourth preference (in order of increasing cost).
When the trunk you selected as first preference is busy, the system will route the call through the next
trunk you have set that is free.
• Refer to the table you prepared for assigning Cost Factor to trunks.
• For example, you want calls made during 9am to 8pm to be routed through BSNL trunks (CO1 and CO2).
If these trunks are busy, you want the system to route calls through the BSNL mobile trunk. When this line
is busy, you want the system to attempt to route calls through the line of Reliance.
