How to change soft input panel (SIP) to digits only?

Question

I've use the "Digits" and "Numeric" input scopes on the emulator for windows phone7 but on the actual device it ends up being the default input scope.

How do I change it to "Numeric" on the actual device? Is there something that I'm missing?

Answer 1

InputScope="TelephoneNumber" works on both Mango and NoDo.
