Local Contacts Backup - Yealink SIP-T3 Administrator's Manual

Administrator's Guide for SIP-T2 /T3 /T4 /T5 /CP920 IP Phones
On T57W/T48U/T48S/T48G phones, when uploading a contact avatar, you can also upload a contact icon named
the same as this avatar, since a one-to-one correspondence between the icon and avatar. For example, an icon file
and avatar file both named "Lily_photo.jpg" are available on the phone, the contact with specified default_pho-
to="Lily_photo.jpg" will use the corresponding name "Lily_photo.jpg" as directory icon and avatar display.
The following shows the custom contact Lily with corresponding avatar and icon display:
Note
: If you have configured to back up the local contacts to the server, the phone will download the contact file "<MAC>-con-
tact.xml" from the backup path from the server and display the downloaded contacts in the local directory list. The contacts in
the local contact file "contact.xml" downloaded from the provisioning server do not take effect.

Local Contacts Backup

Yealink phones support storing all local contacts to a contact file named <MAC>-contact.xml. You can back up this
file to the server, avoiding data loss. Once the contacts update, the phone will automatically upload this file to the
provisioning server or a specific server. If a contact file exists on the server, this file will be overridden. The phone
will request to download the <MAC>-contact.xml file according to its MAC address from the server during auto pro-
visioning.
The contact file is named after the MAC address of the IP phone. For example, if the MAC address of an IP phone is
00156574B150, the name of the contact file is 00156574B150-contact.xml (uppercase).
Tip
: MAC address, a unique 12-digit serial number is assigned to each phone. You can obtain it from the bar code on the
back of the phone.
The following table lists the parameters you can use to back up the local contacts.
Parameter static.auto_provision.local_contact.backup.enable <y0000000000xx>.cfg
