FIELD: physics, computer engineering.
SUBSTANCE: invention relates to means of changing direction of flow. After establishing a connection with a device, a control server reverses the direction of message flow between the device and the control server such that the device becomes the initiator of the call (the caller) and the control server becomes the device which is called (the callee). A connection is also established between a first device, the control server and a second device which is an endpoint for the call. Initial multimedia data and forking are available to the first device after reversing the direction of message flow between the first device and the control server and the callee has been contacted. Additionally, information flows between the first device and the second device through the control server as if the first device and the second device were directly connected.
EFFECT: shorter time for changing the source of the flow of messages; the control server initiates calls to the first device.
