Least-Cost Routing Operations
Least-cost routing (LCR) allows the CMA system to route ISDN or POTS calls
made on paths that incur the lowest expense. You can route calls from one site
through a gateway in another site by referencing LCR tables.
Least-cost routing is useful when sites already have a high-bandwidth
connection between them.
Least-cost routing works with the CMA system’s other routing features.
Setting up least-cost routing requires you to:
• Determine the LCR information to enter in the CMA system.
• Create LCR tables.
• In the device record for MCUs:
— Define an H.320 service and select the LCR table to use.
— Define a gateway service and select the H.320 service associated with
the LCR table.
Note
Make sure the LCR tables you define match the network setup.
