Hi Ricardo,

Have you looked into using this CME Feature?

System Message Display

The System Message Display feature allows you to specify a custom text or display message to appear in the lower part of the display window on display-capable IP phones. If you do not set a custom text or display message, the default message "Cisco Unified CME" is displayed.

When you specify a text message, the number of characters that can be displayed is not fixed because IP phones typically use a proportional (as opposed to fixed-width) font. There is room for approximately 30 alphanumeric characters.

The display message is refreshed with a new message after one of the following events occurs:

Busy phone goes back on-hook.

Idle phone receives a keepalive message.

Phone is restarted.

The file-display feature allows you to specify a file to display on display-capable IP phones when they are not in use. You can use this feature to provide the phone display with a system message that is refreshed at configurable intervals, similar to the way that the text message feature provides a message.

The difference between the two is that the system text message feature displays a single line of text at the bottom of the phone display, whereas the ***system display message feature can use the entire display area and contain graphic images.
