Configuring the Endpoint for NENA Devices
1. From Scout Manager's Configuration tab, in the Endpoints folder, select Add New > Endpoint.
2.
Right-click the new endpoint that displays under the Endpoints folder and select Properties (or double-click the
new endpoint).
The Endpoint Editor dialog box displays.
3.
Configure the endpoint's settings as appropriate. Verify that the Endpoint Profile that you assign to this
endpoint is consistent with the way you want the endpoint to operate.
IMPORTANT
This endpoint is considered a "media workstation endpoint" and not a "VPGate endpoint" because the
interface is directly connected to the console through a USBcable, and not through a VPGate. The Name
you assign to this endpoint should be unique from other VPGate endpoints that are on the same domain.
