Keypad interface for adding new extensions

I'd like to see a keypad interface when creating new extensions, this simplifies the process of finding a vanity number for new users.

Describe the solution you'd like
Instead of a regular input box, a button matrix representing a telephone keypad would be awesome.

If we do this, you could no longer enter your vanity number by using characters (e.g. PHONE) but instead have to lookup the correct numbers (e.g. 74663).

I see, but I wasn't aware that it's even possible to enter a vanity number by using characters. Under these circumstances, I'd say a short info text pointing out that characters can be entered is sufficient and the keypad idea is redundant and would just be eye candy.
