Cancel out of voice prompts back to the operator

My boss wants to be able to cancel out of the voice prompts that come default and go back to the operator/IVR.

When you call someone and they are not at their extension, you get the voice prompt on mailbox instructions and there is no way to cancel and call another number instead. It can be frustrating when you would like to dial another extension when the person isn’t there and instead you have to wait through the first voicemail instructions message, cancel out of leaving a message, then listen to the prompt that says you are going back to the main menu.

Any ideas on how to shorten this wait would be very appreciated.

By the way, we have just started using asterisk/freepbx and it is a great product so far. freepbx helps get someone unfamiliar up and running quickly.
