Comdial Corporation was taken over by Vertical after it declared bankruptcy. The digital DX phone systems were very popular at the time for small businesses, dependable and with enough features to satisfy most consumers. They were then continued by Vertical and sold through vendors. Vertical branded the systems within their own name and logo. The DX-120 systems can be found with both the Vertical and Comdial names on them, as well as the popular DX-120 telephone handset, the 7261. Regardless of the brand name on the phone they will work with the DX-120 PBX.
