/mcpStep 3 Click Add. The Phone Configuration displays with the universal device template settings filling out the phone configuration. The Product-Specific Configuration section also appears, but with default settings, rather than the existing settings from the phone. Note You can also add the device using the Phone Configuration window's Add New, but this method requires that you enter settings manually. Step 4 DO NOT CLICK Save. If you save settings, Unified CM does not load existing settings from the phone. If you saved by mistake, go straight to the troubleshooting Note at the bottom of this procedure for recovery steps. Step 5 Register the phone. During registration, the existing Advanced Configuration settings from the phone get pulled into Unified CM and display in the Phone Configuration window's Product-Specific Configuration section. Step 6 In the Phone Configuration window, configure how you want endpoint settings to be managed by configuring the Configuration Control Mode field: • Unified CM and Endpoint (Default)—Use this mode if you want Unified Communications Manager and endpoint to operate as the multi-prime source for provisioning endpoint data. If Unified CM and Endpoint is the configured mode, any update made via an endpoint locally is synched with the Unified CM , and any change made on Unified CM syncs to the endpoint. • Unified CM—Use this mode if you want Unified Communications Manager to operate as the centralized primary source for provisioning endpoint data and does not want to accept any configurations done from the endpoints locally. • Endpoint—Use this mode if you want endpoints to operate as the centralized primary source of configuration data. In this mode, the endpoint maintains existing settings, ignores any configuration data from Unified Communications Manager, and doesn’t sync back the changes done locally. This mode is typically used when an Audiovisual (AV) integrator is installing the endpoints and wants to control configuration from the endpoint. Note If you want to maintain existing settings on the endpoint, it's recommended to choose Endpoint mode, at least until after the endpoint has completed the registration process in full. You can switch the configuration to one of the other modes after you complete this procedure. Step 7 Configure any phone settings that you want. For more information on the fields and their configuration options, see Online Help. Step 8 Click Save. The provisioned settings in Unified Communications Manager download to the endpoint.
