Android phones don't always display the dial pad during a call. If you're calling an automated system, you'll need the dial pad to make selections. Here's how to display the dial pad during the call, as well as set up the Droid X to launch the dial pad automatically for specific numbers.
Manually launch dial pad
If you need the dial pad during a call, simply select the "Dialpad" button on the lower right-hand side.
Automatically launch dial pad
If you'd like to set up custom numbers and/or service numbers (voice mail, toll-free numbers, and 900 numbers) to display the dial pad automatically when dialed, follow these steps:
Press the Home Key on your phone and select "Settings."
Select "Call settings."
Scroll down and select "Show dialpad."
If you want the dial pad to display automatically for voice mail, toll-free numbers, and 900 numbers, check the "Service numbers" option. If you want the dial pad to display for all calls, check the "All calls" option.
To set up custom numbers, check the "Custom phone number" option and select the drop-down arrow next to "Entered custom numbers."
These directions should apply to most Android phones, but they may differ slightly.
