Backing up the Call Logs
Yealink IP phones support storing all call logs to a call log file named <MAC>-calllog.xml. You
can back up this file to the server, avoiding data loss. Once the call logs update, the IP phone
will automatically upload this file to the provisioning server or a specific server. If a call log file
exists on the server, the file will be overridden. The IP phone will request to download the
<MAC>-calllog.xml file according to its MAC address from the server during auto provisioning.
The call log file is named after the MAC address of the IP phone. MAC address, a unique 12-
digit serial number assigned to each phone, can be obtained from the bar code on the back of
the IP phone. For example, if the MAC address of an IP phone is 00156574B150, the name of
the call log file is 00156574b150-calllog.xml (case-sensitive).
It is not applicable to CP860 IP phones.
