In a communication apparatus for a communication network, a call distribution unit distributes calls that come in for the communication network to a corresponding switching equipment unit, which is provided for accepting the calls and for forwarding the calls. The switching equipment unit comprises a different control unit, whereby a first type of control unit is responsible for calls of lower priority and a second type of control unit is responsible for calls of higher priority. When a corresponding interrogating key is operated, the calls of higher priority that are pending at the second control unit are accepted, whereas calls of lower priority that are pending at the first control unit are only accepted when calls of higher priority are not pending at the second control unit when corresponding call acceptance units are operated.
