Partner ACS Group Calling & Hunting

[NextProblem]

I have a customer with an ACS,they have 2 groups of 3 phones each(calling groups 1 & 2). All incoming calls are answered by the AA. Pressing 9 performs a direct extension transfer to 71(calling group 1). If unanswered the customer wants the call to go to the second call group (72). I tried to build a hunt group for this but the system will not allow me to enter 71 & 72 as extensions. any thoughts?

I only have time to do it right.
I don't have time to do it twice!
