Routing Index
3
4
The device calculates the optimal route in the following index order: 3, 1, 2, and then
4, due to the following logic:
•
Index 1 - Cost Group "A" has the lowest connection cost and minute cost
•
Index 2 - Cost Group "B" takes precedence over Index 4 entry based on the first-
matched method rule
•
Index 3 - no Cost Group is assigned, but as the 'Default Call Cost' parameter is
configured to Lowest Cost, it is selected as the cheapest route
•
Index 4 - Cost Group "B" is only second-matched rule (Index 1 is the first)

Example 3: This example shows how the cost of a call is calculated if the call spans
over multiple time bands:
Assume a Cost Group, "CG Local" is configured with two time bands, as shown below:
Cost Group Time Band
TB1
CG Local
TB2
Assume that the call duration is 10 minutes, occurring between 16:55 and 17:05. In
other words, the first 5 minutes occurs in time band "TB1" and the next 5 minutes
occurs in "TB2", as shown below:
Figure 15-39: LCR using Multiple Time Bands (Example)
The device calculates the call using the time band in which the call was initially
established, regardless of whether the call spans over additional time bands:
Total call cost = "TB1" Connection Cost + ("TB1" Minute Cost x call duration) = 2 + 1
x 10 min = 12

15.4.2 Configuring LCR

To configure LCR, perform the following main steps:
1. Enable LCR - see Configuring a Gateway Routing Policy Rule on page 525 (for
Gateway) and Configuring SBC Routing Policy Rules on page 715 (for SBC).
2. Configure Cost Groups - see ''Configuring Cost Groups'' on page 270.
3. Configure Time Bands for a Cost Group - see ''Configuring Time Bands for Cost
