Having an odd issue that calls that are transferred to an ACD group from Auto Attendant or via live transfer are not following the ACD Hunt Group programming. The calls never hit the mandatory greeting and will recall back to whatever performed the transfer. Calls directed straight to the ACD Hunt Group via DID function properly. This system is an old 14.67 IPX 500 with a Simplicity voicemail. I have tried to get the customer to upgrade numerous times throughout the years, but they have always turned down upgrades. Any ideas what may be causing this issue that I should look at?
