This invention presents a service of barring the forwarded calls. According to the invention, a subscriber may define in his subscriber information that all calls forwarded to him are to be rejected. In response to receiving a request for establishing a call to a subscriber, his subscriber information is checked to find out if he has defined that calls forwarded to him are to be rejected. If the subscriber information shows that the subscriber wishes to reject the forwarded incoming calls, the call establishment signaling is studied to find out if the call has been forwarded. If the call is determined to have been forwarded, the call is rejected. In a preferred embodiment the subscriber may define a set of allowed numbers from which even the forwarded calls are to be accepted.
