Route Lists in Webex Calling are lists of numbers reachable through a Route Group. Each Route List is exclusively assigned to a Location that supplies up to 40,000 unassigned numbers from the hosted pool.

Only customers with Dedicated Instance entitlements can see or configure Route Lists in Control Hub.

Route Lists to a single DI cluster

The figure above illustrates a Webex Calling organization with two Route Lists in their respective locations (SJ & DFW), each of them pointing to the same Route Group/Trunk, which in turn routes to a single Dedicated Instance cluster.

Figure 2. Route Lists to multiple Dedicated Instance clusters

The figure above illustrates a Webex Calling organization with two Route Lists in their respective locations (SJ & DFW), each of them pointing to different Route Group/Trunk configurations, which in turn routes to two different Dedicated Instance clusters within the same customer organization.
