An engineer must configure a dial plan tor a new Cisco UCM cluster. Standard local route groups must be used for all local calls. After the route pattern, route list and route groups are configured…

In Cisco UCM, "Standard Local Route Group" is a setting within the Device Pool configuration. When a route group is set as a standard local route group, it uses the Route Group defined in the device pool associated with the calling device (phone). Therefore, for standard local route groups to be effective, the correct device pool must be configured and assigned to the relevant devices, and the device pool itself must point to the appropriate local route group list.

A voice gateway is a termination point for calls, but the setting for associating a specific route group as "standard local" is within the device pool, not directly on the gateway itself.

A trunk group is a logical grouping of trunks and is not the parameter that defines how "standard local route groups" function from a device's perspective in UCM.

A SIP trunk is a specific type of trunk used for call routing, but the mechanism for standard local route groups is managed via device pools, not directly on the SIP trunk configuration.
