T54S/T52S/T48G/T48S/T46G/T46S/T29G IP phones:
Scenario A - Using the Built-in Avatar for Contact
This scenario is applicable to SIP-T54S/T52S/T48G/T48S/T46G/T46S/T29G IP phones.
To customize a local contact file:
1. Open the template file using an ASCII editor.
2. For each group that you want to add, add the following string to the file. Each starts on a
separate line:
<group display_name="" ring=""/>
3. For each contact that you want to add, add the following string to the file. Each starts on a
separate line:
<contact display_name="" office_number="" mobile_number="" other_number="" line=""
ring="" group_id_name="" default_photo=""/>
4. Specify the values within double quotes.
For example:
<group display_name="Friend" ring="Splash.wav"/>
<contact display_name="Lily" office_number="1020" mobile_number="1021"
other_number="1112" line="1,2" ring="Ring1.wav" group_id_name="Friend"
default_photo="Resource:icon_family_b.png"/>
5. Save the change and place this file to the provisioning server.
6. Specify the access URL of the custom local contact template in the configuration files.
For example:
local_contact.data.url = tftp://192.168.10.25/contact.xml
During the auto provisioning process, the IP phone connects to the provisioning server
“192.168.10.25”, and downloads the local contact file “contact.xml”.
Note
If you have configured to back up the local contacts to the server, the IP phone will download the
contact file “<MAC>-contact.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 don’t take effect. For more information on how to back
up the local contacts, refer to Backing up the Local Contacts on page 367.
