I am starting with Asterisk and have been reading the tutorials on IVR. I followed the examples and fine so far.
Now I want to change the behaviour a bit for invalid keys ( i: Invalid entry extension).
If the caller presses a key while in the menu prompt that has not been assigned any extension, I want it to do nothing. Nothing in my case means:
- keep playing the menu prompt in backround()
- keep waiting for valid input from the caller
Is that possible?
How do I have to go about it?
Thanks a lot!
