I don't know that this is a "strange" solution... I've been doing this for years...
But I'm going to pass along a secret that will be a lifesaver... this is a top-secret trick passed to me in a whisper at midnight under a full moon by a certified Toshiba tech support renegade...
You can call forward a multiple call group.
Yes... you can, for example, on MCG group 800, you can do something like #6032800#vm pilot#30
If you're trying to do - for example, with an MCG group - one set of phones immediate ring, second group of phones delay one, third group of phones delay 2, *THEN* to Voicemail - this trick will save you.
