joshsullivan:
1. Create a HG, with VM
2. put only an analog phone in the HG. It can actually be any phone type (digital if you want), key is that there must be an actual phone attached (otherwise call will go immediately to VM). I use an analog phone with the ringer off, leave it hidden in the phone room somewhere.
3. point ICR at the HG
4. add Hxxxx source numbers to all users who need to see the HG VM on their MWI's
5. assign line appearances to users for the same lines which target the HG via the ICR.
The effect is that the users only see their line appearances alert, once the no answer timer expires, the caller goes to VM and the MWI's lite up. The users DON'T see calls coming in on both LA's and CA's, as they aren't actually in the HG targetted by the ICR. This removes one source of confusion related to using LA's on the IPO.
Because the ICR targets a HG, you can do all the usual trickery involving time profiles, AA/SC/Phantom/HG/buttons stuff you'd usually do to control afterhours callflows etc.
