20. LCR

Estimated reading: 1 minute

The LCR (Least Cost Routing) section allows fine-tuning of the system's line usage. By default, the system uses default trunks for each destination in order to present this feature as simply as possible.

This thus allows you to prioritize a trunk for a specific route.

Routes

Displays all available destination routes in alphabetical order.

Primary/Secondary/Tertiary Trunk

Select the trunks to use for the desired destination.
If the connection is not established through the primary trunk, the trunk will be used, and so on.

E164 routing

When E164 routing is configured on the system, the LCR section is presented differently.

The routes are then the groups of destinations (for example, countries) sorted in alphabetical order.
