You have to use the traditional phone keypad letter-to-numeric mapping (look at your phone).For example, if the account number is a123g, you would expect the customer to enter:
21234
Of course, this sequence can also be:
c123i
and lots of others, especially if the letters do not have fixed positions in your account id.
Then to validate the account number, you would need to ask for a password, and then to check if it matches at least one of the account in your DB, which is a security risk.
I would say it is minimal, but it depends on the application.
That's probably why all the services using DTMF always ask for numeric-only accounts and passwords.

Hello Brian,
It's an IVR which asks for an alpha numeric account number. But I am able to send it from xlite and the same is getting recognized, only when I am trying it through api it's not recognizing.
Otherwise suggest me an alternate
Thanks, Rex
