IP решения
MSG-1 IP-telephony gateway is designed to provide telephony features at the intersection of data networks with IP packet switching and EDSS1 circuit switching. For this purpose, MSG-1 performs signal information processing from the circuit switching networks and its transfer over IP-network (VoIP technology), as well as flow control for voice transfer and data in multiservice networks.
