Ivr and information about caller's choice


I have made an ivr (Interactive Voice Responce systems) like this:

(it’s an example)
"Hi, if you have dog please tape 1 or if you have cat tape 2"
the two choices redirect on the phone 101
But I want to know the caller’s choice.

How to do this?


unless you can modify the from field after they make a selection, I don’t think you will be able to determine who is calling and what option they pressed. I am eager to find out if this can be done though, I have heard it a few times in the passed and didn’t ever see a resolution.


Tnaks for the response.
I have find, I fact you must create a ring group and add a prefixe to the number.
And in the ivr, link to the ring group in case of choice.
