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 domain. 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 prop-
erly configured in MaxAdmin:
• 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.
