I have a customer with a legend. I have a configuration that is in place now and want to know if there is a better way to accomplish what they want.

Right now,

Call comes into receptionist. Recep transfers to a hunt group (398). 2 phones in group 256 and 288. 256 has icom voice and ring buttons and shared access buttons for voice and ring on 288. 288 setup the same. after 4th call, it goes straight to voicemail. They would like more calls to be passed through before going to voicemail. There a better way to accomplish this? A different button perhaps. Can I put a button on the phone for 398, the hunt group number?
