I once tried to use two digits to enter an alpha (21 for a, 22 for b, etc.) but it failed.
Same way as you'd call 1-800-united-1, just one key press per letter corresponding to the letter desired. A, B, or C are mapped to 2. (Yes, you can't go from number to letter unambiguously, but the entire set gives enough context.)
