A method for establishing a speech path between a terminal, which is operating using circuit-switched protocol, and a mobile services switching centre, MSC, server, wherein the MSC server comprises a mobile services switching centre for circuit-switched connections and an interworking function adapting the mobile services switching centre for packet-switched connections in a telecommunications network (HPLMN, VPLMN) comprising access networks and core networks, wherein an access network comprises an access network node, which is radio network controller or a base station, the access network node operating as a circuit-switched element to the terminal and as a packet-switched element to an uplink to a packet-switched network in said telecommunications network (HLPMN, VPLMN); the method comprising the steps of: receiving, at the access network node a first initiation signal from the terminal, the first initiation signal being an attach request signal or a request for call setup; opening, in response to the first initiation signal, between the access network node and a support network node in the packet-switched network, a first connection for the terminal, the first connection being a packet-switched connection, the opening including establishing a first packet data protocol, PDP, context, which is a signalling PDP context (3-4... 3-18) or a real-time PDP context; receiving, at the access network node, while the first connection is active, a second initiation signal, the second initiation signal being a call request to establish a voice call to/from the terminal and is used by the access network node to establish a speech path for a call between the terminal and the MSC server; wherein the establishing comprises establishing, in response to the second initiation signal, a second connection by opening, by the access network node and the support network node, a second PDP context, which is a real-time PDP context, suitable for conveying speech, and a tunnel (3-12, 4-16) between the MSC server and the support network node in the packet-switched network; using, by the access network node, the second connection to relay speech or signalling for the speech path between the terminal and the MSC server. receiving, at the access network node a first initiation signal from the terminal, the first initiation signal being an attach request signal or a request for call setup; opening, in response to the first initiation signal, between the access network node and a support network node in the packet-switched network, a first connection for the terminal, the first connection being a packet-switched connection, the opening including establishing a first packet data protocol, PDP, context, which is a signalling PDP context (3-4... 3-18) or a real-time PDP context; receiving, at the access network node, while the first connection is active, a second initiation signal, the second initiation signal being a call request to establish a voice call to/from the terminal and is used by the access network node to establish a speech path for a call between the terminal and the MSC server; wherein the establishing comprises establishing, in response to the second initiation signal, a second connection by opening, by the access network node and the support network node, a second PDP context, which is a real-time PDP context, suitable for conveying speech, and a tunnel (3-12, 4-16) between the MSC server and the support network node in the packet-switched network; using, by the access network node, the second connection to relay speech or signalling for the speech path between the terminal and the MSC server.
