[Asterisk-Users] translate letters into digits

[Armin Schindler]

Hi,

I was wondering if there is already an application or a simple
mechanism to convert the dialed extension into digits if letters were used.
I don't know if there is a name for that, I mean the letters on the phone
keypad: ABC=2, DEF=3, ...

So when I call e.g. JOE, the extension 563 shall be used.

Do I need to write my own little application to accomplish this?

Thanks,
Armin
