A call center service is offered in a peer-to-peer network. At least one peer in the peer-to-peer network has a call center function added to it, and a check is then carried out by way of a search algorithm to determine whether a called subscriber is or is not registered in the peer-to-peer network. If the called subscriber is registered, an IP address is first of all determined for that subscriber, and a check is then carried out to determine whether the call center service has been activated for this subscriber. An incoming call is then diverted to a peer with a call center function, and is not passed on to the called subscriber until contact is made with the peer with the call center function. Otherwise, if the subscriber is not registered in the peer-to-peer network, further entries for the called subscriber are first of all checked in the peer-to-peer network. If there is an entry for an active call center service, an address of a peer with a call center function is sought, and the incoming call is then forwarded directly to that peer with the call center function.
