asterisk users - Nov 2011 - Displaying entered digits in the LCD of the IP Phone when is requested to enter it

Hi All;

When using the IP Phone and will be prompted to enter a digits (for example,
using the Background function), so when dialing the digits, I do not see these
digits on the LCD of the Phone, how can I make it appear?

Actually I need it because I have a Background funtion that ask the agent to
enter the number (through some scenario), so when dialing it, we would this to
appear at the LCD of the phone, how?

Regards
Bilal
