How do I change the dialing from pulse to tone? (Tone dialing is faster than Pulse Dialing)

To change the dialing from pulse to tone:
Go to the 'Control Panel'.
Double Click 'Phone & Modem Options'.
The 'Dialing Rules' tab will be displayed probably with only one location on the list.
Select the 'location' and click 'Edit'.
Choose 'Tone dialing'.
