The invention relates to a method for anonymizing the communication of mobile terminals which permit speech communication, using an anonymizing network which comprises a series of routers and which has at least one access node, wherein each mobile terminal establishes a connection with at least one access node, comprising the following steps: signing the mobile terminal onto the network via an access node; preparation of an identity in the network; communication via the anonymized network, wherein the network selects different random routes through the network for communication, so that back-tracing is prevented and wherein communication is encrypted.
