The OpenScape Desk Phone CP400T is considered as the phone for the standard office workplace. The device itself already provides 16 freely programmable function keys with colored LED (green) status indication, three of these keys are pre-assigned with the functions message, redial and disconnect. The paper label reduces the costs and takes into account the customer’s request for many keys. The OpenScape Desk Phone CP400T uses the standard Key Modules KM400, which were already introduced with the OpenScape Desk Phone IP portfolio. It can be extended with up to two Key Modules KM400. This gives users direct and quick access to their functions-, name- or linekeys.
