I think I already know the answer, but...
On our VMPro configuration we have it set such that a call comes in and is received by the auto-attendant. During the greeting, the caller can press 1 for sales, 2 for order status, etc... After pressing a number, the caller is then transferred to the correct Hunt Group and they hear Music on Hold. Is it possible that while hearing the MoH for 3 or 4 minutes, they can hear greeting #2 (all agents are busy, blah blah...) and have the option of pressing 5 to get transferred OUT of the hunt group to an extension to leave a message? I am not sure that this is possible becuase there is no place during MOH to accept input...
If this is NOT possible, whould you suggest a different method to make this possible?

Thanks
