Abstract
Systems and methods provide a unified call log for user devices in a device group. A user device receives an invite message for an incoming call and stores first call log information including a caller identifier based on the invite message. The user device receives a status message indicating that another user device has answered the incoming call and stores second call log information including a timestamp for the status message. The user device receives a call information message for a new line between the user device and a device associated with the caller telephone number, determines that the new line is a handover call associated with the incoming call, and stores third call log information for the new line. The user device determines that the handover call on the new line is ended and generates a call log entry including information from the incoming call and the handover call.
