When IP phone A was provisioned in a Cisco Unified Communications Manager, 2001 was configured as the directory number for its first line.
Also, bob@cisco.com was defined as the only directory URI on the Directory Number configuration page for this line.
A few days later, an end user was created in the same Cisco Unified Communications Manager and was associated with the same phone with the primary extension set to 2001
Also, bobby@cisco.com was defined as a directory URI for that end user.
Which option about the primary directory URI for IP phone A is true?

In this scenario, an IP phone A was provisioned with a directory number (DN) 2001 and a directory URI "bob@cisco.com". Later, an end user was created and associated with the same phone with the primary extension set to 2001, and a directory URI "bobby@cisco.com" was defined for the end user.
Directory URIs are used for Unified Messaging and are associated with directory numbers. They can be used to direct incoming calls to the appropriate device or application, such as voicemail or email. The primary directory URI is the default directory URI for a directory number.
Based on the information provided, we can conclude that the primary directory URI for the IP phone A depends on which radio button was selected next to the directory URI entries on the Directory Configuration page.
If the radio button for "Use directory URI from line" was selected, then the primary directory URI for the IP phone A is "bob@cisco.com". This is because the directory URI defined for the directory number takes precedence over the directory URI defined for the end user.
If the radio button for "Use directory URI from user" was selected, then the primary directory URI for the IP phone A is "bobby@cisco.com". This is because the directory URI defined for the end user takes precedence over the directory URI defined for the directory number.
Therefore, option C, "It depends on which radio button was selected next to the Directory URI entries on the Directory Configuration page," is the correct answer. Options A and B are incorrect because they assume that one directory URI takes precedence over the other, which is not necessarily the case. Option D is incorrect because both directory URIs cannot be primary directory URIs for the same DN. Option E is incorrect because there are directory URIs associated with the IP phone A.
