IVR auto attendant extension assignment

How do I assign extensions to the IVR auto attendant?

My main menu is using entries for 1-9… I would like to assign extensions starting with 201… but when I make the key prompt 201… it tells me 2 is already being used by another menu item.

Yes, the error message is correct.

Let’s assume the software allows you to have 201 for an extension, and 2 for replay the message. So when the caller presses 2, the system finds a match and will replay the message. It will never get to extension 201.

You can either introduce another level of choice menu, or do not use 2 for other choices.
