Branodnt.theisen,
I was going to ask why you are using the NuPoint, but that is not going to solve your problem. Now, bear with me as I have never actually had to make a NuPoint work with a 5000, but I do know that it works so this shouldn't be too difficult.
So the first thing would be creating a box with the same extension as the hunt group. We need to do this so when the call is sent to the voicemail HG it will send the digits of the hunt group it will match with something in the NuPoint.
Then you will need to create a call flow off of that mailbox that sends the caller to the mailbox that you really want it to go to.
If you need specifics on how to do that then I can move your post to another group as the NuPoint is not really used much on the 5000, read not at all, in our installations as it is not as "good" as the built in voicemail system.
Thanks,
TE
