Abstract
Method for setting up telephone-to-telephone calls using telephones connected to a PSTN/ISDN access network and using a separate packet-switched network as a by-pass network, wherein telephone gateways (GW) provide bridges between the access network and the by-pass network, and connections are established between a calling party (A) telephone and a first gateway (GWa) and between a second gateway (GWb) and a called party (B) telephone. The method includes the steps of: dialing, by a calling party (A) in a one-step procedure, a by-pass network service prefix together with the number of a called party (B), wherein the by-pass network service prefix includes an IN-service prefix; and analyzing the by-pass network service prefix to identify the relevant IN service for thereby routing the call to an IN node which can execute the IN service, the IN service establishing a call to a first gateway (GWa) selected from one of a plurality of gateways (GW), whereby the first gateway is made service transparent to the calling party (A).
