Hi Acktel,
No way I know of unless you upgrade to ACS 3.0 or higher. Earlier ACS may do this, but you may as well go this far for remote access.
You could ring a port and set it for delayed ring, plug it into another CO port that you don't see on the system and cover that with VM instead of the original line(s). You may be able to get away with only doing the first few CO's. That will get you 7 ish rings.
