[Asterisk-Users] Text entry by DTMF

[Steve Underwood]

Hi,

I've kind of ported a DTMF text extry method I wrote some time ago for 
Dialogic. It is now a semi-working Asterisk app. I've still got to clean 
up some stuff in how Festival is used to read back what is entered, and 
then I think it should be OK.

Would anyone here find this useful? It takes an entered string, and 
returns it as a variable. It might sound clunky, but for short entry of 
things like names, it actually works quite well. What I am looking for 
right now is ideas on what people might need in such a facility, to I 
can tie down the loose ends. Right now it takes:
    - a variable name to be used when returning the string
    - some pre-existing entered digits, that might have come from a 
previous step in a sequence of activities (e.g. if you press a digit at 
a menu prompt, you might what that digit to be the first digit of the 
text entry process).
    - the maximum length of the entered text
    - an overall timeout, so the entry cannot go on forever.

The software uses Festival to read back what is entered. It has numeric, 
lower case, upper case and symbol modes, and can switch freely between 
them. The entry technique has been field proven in the Dialogic version.

Any useful input much appreciated.

Regards,
Steve
