Sorry, you got the wrong phone system.
There are ways to trick it.
One would be press 1 transfer to an ext with a loud ringer or strobe that the group can see or hear, then do a directed pickup to answer call.
There are hunt groups, but only circular or terminated, and always start with the same ext and hunt in the order.
In above setup you could have multiple ext with ringers in a hunt group if you are real busy.
You also need more VM ports. Latest firmware will let you run 4 ports APITS.
