Outbound route is what binds the numbering plan with the trunk in Genesys Cloud CX Telephony Admin menu. An outbound route is a logical connection that allows voice communication from Genesys Cloud CX to an external system or network using a trunk. An outbound route can have various options configured to define its behavior and performance, such as:

Numbering plan

Trunk

Classification

Priority

An outbound route binds the numbering plan with the trunk by specifying which numbering plan and which trunk to use for outgoing calls based on the classification of the destination number. An outbound route can also specify the priority of the trunk to use when multiple trunks are available for the same classification.
