Sorry - couldn't resist this :
When you pick up the phone, and get a dialling tone, press the keypad in sequence for each digit of the telephone number you want to dial - this should accomplish what you have asked.
If your phone is an older type : Stick your finger in the dialling hole corresponding to each digit of the number you want to dial and rotate clockwise to the stop. Let go and when the dial has returned to its start position repeat in sequence for the remaining digits.
.... but I guess that isn;t what you meant ???
