Configuring Global Least Cost Routing
Global LCR allows you to save on toll charges by making long distance or international calls through a VoIP
domain member system. The target system will function like a PSTN gateway for other member systems to
hop-off. For example, suppose you have two systems in the U.S. and one system in the U.K. configured as
VoIP domains. When users in the U.S. dial country code 44, you want the call to be dialed though the system
in the U.K. to its PSTN network.
Global LCR has higher priority than local outcall routing. The system will check the Global LCR entries first
before the call is handled by the local system's outcall routing rules.
Before you configure Global LCR, you need to evaluate the following conditions:
•
How many concurrent calls will be routed through the target system?
•
Does the target system have enough PSTN trunks to support the entire VoIP domain?
•
Does the target system have enough WAN bandwidth to support system-to-system and PSTN hop-off
calls?
Before you configure Global LCR, you need to make sure the following settings are properly configured in Max-
Admin:
•
Both systems need to have the route access code configured on the Number Plan tab in System
Configuration. (The user has to dial the route access code + the phone number to use Global LCR.)
•
The target system needs to have the hop-off restriction reference properly configured. The reference
extension is set on the Call Restriction tab in System Configuration, and then that reference extension
cannot have Internal Calls Only checked on the Restriction tab of Extension Configuration.
