You should not exchange phones of different types since the types and related functions are centrally configured on the telephone system. If an exchange should be necessary, please submit an application for relocation.
Please make sure that all cables are connected to the phone, receiver and socket.
You can determine whether the disturbance is caused by the device by swapping with a device of the same type (if available). If the disturbance is systemic you can report it to the fault-clearing service.
The name entries are transferred from the CAMPUS system of the RWTH onto the TC system at regular intervals. Therefore, in case of an incorrect display of the name, please initially check the correspondingentry in the CAMPUS system. Modificationscan be made by the person entitled to change phone book entries.
By the way: Should you not be satisfied with the default display indicator, you can choose another label in the field "phone display" on the CAMPUS modification page. Each phone number is granted ONE entry. This will not affect the institution token.
