I am in the process of upgrading a customer from a Norstar MICS to an IPO V 6.1. They currently use HG appearances on the phones so they can Fwd to Voicemail for incoming DID calls but the hunt group calls will still ring in. I am trying to duplicate this on the IPO but the users have DND and when the users in the Hunt group set their phone to DND the hunt group calls ring busy. I tried a DND exception adding the hunt group ext but that did not work. Calls still ring busy. Help????
