Phone Information and Display Settings
Procedure
Step 1 Click Admin Login > advanced > Voice > Phone.
Step 2 To display a text logo, enter text in the Text Logo field with following requirements:
• Enter up to two lines of text.
• Each line must be less than 32 characters.
• Insert a new line character (\n) and escape code (%0a) between the two lines.
For example,
Super
Telecom
• Use the + character to add spaces for formatting. You can add multiple + characters before and after the
text to center it.
Step 3
To display a picture logo:
• Enter the path in the PNG Picture Download URL field.
For example:
http://10.64.84.147/pictures/image04_128x48.png
The supported phone image file attributes are: Bitmap format, one bit-per-pixel color, size 128-by-48
pixels. You can also use a TFTP server.
• Change Select Logo to PNG Picture.
Step 4 Click Submit All Changes.
The phone reboots, retrieves the .png file, and displays the picture when it next boots.
Change the Display Background Picture
You can use a picture to customize the background on the phone screen.
When the PNG Picture Download URL is changed, the phone compares the URL to the previous image URL:
• If the URLs are the same, the phone does not perform the image download.
• If the URLs are different, the phone downloads the new image and displays it, providing that Select
Background Picture field is set to PNG Picture.
The phone does not reboot after you change the background image URL.
A background image displays while the phone is running.
