You may need to turn off wifi and mobile data to send codes.

On most phones there is Call Divert (otherwise called Call Forwarding) option in Call Settings in Settings on the phone.

If busy-if no reply-if not reachable options.

You activate those and in the no reply option you can set the length that way.

This way is far better in my opinion and gives a lot more control when setting up Voicemail.
