Just to double check myself, You have a group of keys programmed on a phone(s) that are in a hunt group.
for example,
Key 1 = 1111
key 2 = 2222
key 3 = 3333
The Pilot number for the hunt group would be 4444.
Delete the hunt group 4444.
remove all key appearances of 1111 and replace with 4444
Create a new hunt group of 1111.
Using Call Rerouting 1st Alt form program to look like this: "This This This This Last Last Last Last 1111"
Now in the Call rerouting second alt form be sure you know which one goes to VM (usually 2)
Next in the Call rerouting assignment form assign your new 1st Alt to ext 4444 with the 2nd alt of 2.
Now put a MWI key on the phones for ext 4444.
