First, if you are going to be going to AGI, why not just ask for the
digits inside of AGI? It seems like it is more appropriate that way.
Read is for when you can accomplish what you want without jumping to
AGI.

Also, be wary that Background will allow a user to interupt the prompt
with a digit press. This is the normal expected behavior. You would want
to use playback.
