FIELD: information technologies.
SUBSTANCE: method of service transportation, which is based on Internet Protocol, consists of the stages at which during the calling process there initiated are requests for service detection by means of the calling gateway controller between transmission media and the called gateway controller between transmission media to their corresponding gateways between transmission media; when the characteristic service signalisation is detected, it is supplied by means of the calling or called gateway between transmission media to gateway controller between transmission media of this calling or called gateway between transmission media, the service type is determined by means of the gateway controller between transmission media according to characteristic signalisation, and codec schemes of the calling gateway between transmission media and the called gateway between transmission media are switched over to the codec schemes corresponding to the service type; the appropriate service transportation type is performed by means of gateways between transmission media by using the codec scheme to which the switching-over has been performed.
EFFECT: improving efficiency of using system resources.
