Explanation

To support a third-party SIP phone in Cisco Unified Communications Manager, three key steps are required on the CUCM side. A is required: you must configure the device (phone) in CUCM, specifying the SIP phone profile, codec settings, and MAC address so CUCM recognizes and communicates with it. C is required: associating the device with an end user links the phone to a directory number and grants the user access to features and voicemail. E is required: configuring the end user in CUCM creates the user account that the device association and features depend on. B (changing the proxy address in the SIP phone) is a step performed on the phone itself, not in CUCM. D (TLS username/password) is only required for secure encrypted deployments, not a basic third-party SIP phone setup. F is incorrect - the SIP phone needs to know the CUCM address, not the other way around.
