Make an extension ring with no device?

[dg]

Hi folks,
I have a user that insists that he wants the caller to hear his phone ringing before it goes to voice mail, despite that he won't ever answer it. While I could just leave this phone plugged in somewhere in a closet, I'm wondering if there's a clever way to program it so it appears to ring even if the phone isn't physically plugged in. Something like forcing the extension to be present when it isn't.
This is on a 3300 + NuPoint/MAS.

Thanks!

Speed ​​call from the did number to an acd path that triggers a rad where you will inject a  . wav tone then after x time forward to voicemail
