asterisk users - Aug 2008 - Read Command

I've search the world over....  but I haven't figured out a way to have
valid/invalid options for entry when using the Read command...

I need to set a variable, but only want to allow certain values to be valid
options for that variable...

Any ideas?

Thanks in advance..

I hope I understand your question.
You can use Read(<var-name>,<msg>,<length of input>);
You can then use switch to control the input.

Alternatively, you can use WaitExten() instead of Read().

Also, try to code your dialplan using AEL2 instead of AEL.

You first use the Read application : 

exten => s,n,Read(ANS|filetoplay)

And then use GotoIfs by checking the ${ANS} variable to do the logic
(re-ask if bad response, else continue in dialplan).

If you use a goto based on the variable afterwards, it should jump to 
the 'i' (invalid) if the option entered does not exist.

Does that make enough sense? If not, feel free to ask more questions....
