Electronic device and method for synchronizing call logs

A server for synchronizing call logs of a plurality of electronic devices configured to share a single phone number, the server comprising:

• a memory including a table storing a plurality of call logs;
• and
• a processor configured to:
• control to receive a call log associated with the phone number from one of the plurality of electronic devices,
• determine whether the received call log has a correlation with the plurality of call logs stored in the table,
• based on the received call log having the correlation, merge the received call log with the stored call logs of the table, based on a predefined condition, to update the stored call logs of the table, based on a merge result,
• based on the received call log not having the correlation, newly store the received call log in the table to update the stored call logs of the table, and
• control to transmit an update result of the table to the plurality of electronic devices.

An operating method of an electronic device configured to share a single phone number with an external device, the method comprising:

• receiving a call request via the phone number;
• transmitting a first call log associated with a missed call to a server in response to a stopped reception of the call request;
• receiving a first response signal regarding transmission of the first call log from the server;
• storing the first call log in a memory of the electronic device based on the first response signal;
• receiving a push signal from the server, wherein the push signal is generated by the server based on a second call log received from the external device and generated by the external device based on the call request;
• and
• changing the first call log stored in the memory to the second call log based on the push signal.
