SIP User's Manual 13. Services
Example 1: This example uses two different Cost Groups for routing local calls and
international calls:
Two Cost Groups are configured as shown below:
Table 13-2: Configured Cost Groups for Local and International Calls
Cost Group Connection Cost Minute Cost
1. "Local Calls" 2 1
2. "International Calls" 6 3
The Cost Groups are assigned to routing rules for local and international calls in the
Outbound IP Routing table:
Table 13-3: Cost Groups Assigned to Outbound IP Routing Rules for Local and International
Calls
Routing Index Dest Phone Prefix Destination IP Cost Group ID
1 2000 x.x.x.x 1 "Local Calls"
2 00 x.x.x.x 2 "International Calls"
Example 2: This example shows how the device determines the cheapest routing rule
in the Outbound IP Routing table:
The Default Cost parameter (global) in the Routing Rule Groups table is set to Min,
meaning that if the device locates other matching LCR routing rules (with Cost Groups
assigned), the routing rule without a Cost Group is considered the lowest cost route.
The following Cost Groups are configured:
Table 13-4: Configured Cost Groups
Cost Group Connection Cost Minute Cost
1. "A" 2 1
2. "B" 6 3
The Cost Groups are assigned to routing rules in the Outbound IP Routing table:
Table 13-5: Cost Groups Assigned to Outbound IP Routing Rules
Routing Index Dest Phone Prefix Destination IP Cost Group ID
1 201 x.x.x.x "A'
2 201 x.x.x.x "B"
3 201 x.x.x.x 0
4 201 x.x.x.x "B"
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
