Indeed, Vodavi has VM's that work off digital ports. A 616 isn't digital.

I guess a 616 meets all the requirments for a VM system, MSG wait, CF-Busy, Flash to transfer, etc., so a good analog VM system and an SLA should be able to control the features.

The problem is that you don't get features like Follow-On-ID, so the auto attendant would have to stay with a call until it was answered, abandoned, or a message was left. Since the 616 has no endearing features, I'd suggest a newer system with better integration.
