The present invention relates to a method of setting up a call matching a predetermined set of requested services and/or characteristics over a network, optionally a network that is composite and multi-component. The method is characterized in that it consists in subdividing said network into a plurality of domains, with a negotiator unit being associated with each domain, in sending to at least one negotiator unit a call setup request together with a set of parameters defining the services and/or characteristics associated with the call to be set up, and, where appropriate, in setting up the call after determining the appropriate available resources in the various domains concerned and selecting resources providing the best possible match with said set of services and/or characteristics.
