The invention relates to a method and a communication system (SYS) for setting up connections from a first terminal (TE) of a first communication network (TCP/IP) to a second terminal (MS) of a second communication network (PLMN). A specific access server (AS) is selected on the basis of the location (LA) of the second terminal (MS) and/or on the basis of call processing related features (CPC) necessary for handling the call in the first and/or second communication network (TCP/IP, PLMN). Thus, always the optimal access server (AS), e.g. nearest to the second terminal (MS) can be selected, together with the appropriate functionalities needed for supporting the call in the networks. The invention is particularly advantageous if the first communication network (TCP/IP) is a packet switched network and the second communication network is a circuit switched network, since in this case the advantages of a packet switching can be maintained as much as possible and the circuit switched call is only needed over the shortest possible distance to the switching means (MSC/VLR) of the second communication network (PLMN). Thus, the resources of both networks are used optimally.
