Scenario B - Using the Custom Avatar for Contact
This scenario is applicable to SIP-T54S/T52S/T48G/T48S/T46G/T46S/T29G IP phones.
To specify custom avatars for contacts, you need to upload the custom avatars to the
provisioning server in advance. In addition, you can also compress all the avatars as a tar
formatted file, and then upload the tar formatted file to the provisioning server.
Preparing the Tar Formatted File
You can package the tar formatted file using the tool 7-Zip or GnuWin32. You can download 7-
Zip online: http://www.7-zip.org/ and GnuWin32 online:
http://gnuwin32.sourceforge.net/packages/gtar.htm. This section provides you on how to
package the tar file using 7-Zip.
To package a tar formatted file using the tool 7-Zip on the Windows platform:
1. Download and install 7-Zip on the local system.
2. Create a folder (e.g., photo) on the local system (e.g., C:\Program Files) and place the file
that will be compressed (e.g., cutom1.jpg, cutom2.png) to this folder.
3. Start the 7-Zip file manager application (7zFM.exe).
4. Locate the photo folder from the local system (C:\Program Files\photo\).
5. Select the desired photos that will be compressed.
6. Click the Add button.
