Abstract: A call control entity (“entity”) communicates with Internet Protocol (IP) phones. Upon receiving from an IP phone a headset connect message indicating that a headset is connected to the IP phone and including a headset identifier of the headset, the entity determines whether there is stored in a call control database a mapping between the headset identifier and a user identifier associated with a user, the mapping configured to provide access to an existing IP phone configuration profile in the call control database. If the mapping exist, the entity completes an extension mobility auto login of the user through the IP phone, which results in acquiring the user identifier from the IP phone. Responsive to completing the extension mobility auto login, the entity accesses the existing IP phone configuration profile based on the user identifier and the mapping, and configures the IP phone with the existing IP phone configuration profile.

Abstract: A call control entity communicates with Internet Protocol (IP) phones over a network. Responsive to a request from a new IP phone that is to replace an existing IP phone, the call control entity determines there is no existing IP phone record for the new IP phone. In response, the call control entity acquires from the new IP phone a directory number associated that is to be used when making calls with the new IP phone, and searches for an existing IP phone record for the existing IP phone based on the directory number. When the existing IP phone record is found, the call control entity creates for the new IP phone a new IP phone record associated with the directory number, copies existing configuration information from the existing IP phone record to the new IP phone record, and configures the new IP phone with the existing configuration information.
