In a communication network in which Session Initiation Protocol (SIP) is used to establish communications sessions with QoS treatment of bearer flows, a method of providing QoS treatment of a bearer flow within a communication session established between two end devices using a different in-band signalling protocol, the method comprising a step of providing a Signalling Inter-Working Function (SIWF) in a path of the in-band signalling between the two end devices, the SIWF being operative to:

  • detect at least a signal state of the in-band signaling; and

    establish a communications session with QoS treatment of bearer flows spanning at least a portion of an end-to-end path between the two end points, based on the detected signal state.
