We have a Comdial DX-80 phone system. I cannot record a new greeting in the automated assistant. When I press record to the automated assistant the phone rings. I do not receive the display message "AUTO_ATT NO.1" like the manual indicates. When I press play the phone rings as well. I have tried to set it up from each phone in the building with the same result. In the control panel, we do not have an AAM Module but there is a module labeled DX-80 VM. I would appreciate any assistance that can be provided.
