Last Release Date: 2019/09/10
Technology: IP telephony


The Russian telephone exchange – program VoIP the platform for the organization of full-function nodes local, zone, communication MG/MN based on IP technology according to regulations of the current legislation.

The solution is certified for application as the node of services implementing using applied subsystems of a signaling system on ОКС№7 functions of switching and management of communication services according to requirements of the Ministry of Information Technologies and Communications of Russia (the registration number of the certificate OS-3-IS-0004).

According to this certificate RTU can be applied as the platform of providing services by the telecom operator in the network built based on any program switches (softsvichy) with the fixed or mobile technology of access and also in convergent networks.

Also the solution completely conforms to requirements of SORM for the mobile and fixed networks, networks of service providers.

The RTU platform can be used by VoIP in quality:

  • full-function switch of class 4/5;
  • platforms for providing services (AS) together with the program switch of other producer in the mobile, fixed or convergent network;
  • SaaS services platforms.

The RTU platform can be used by two methods: as purely service platform, or Application Server in terminology of architecture of IMS, or as a full-fledged node of telephony for providing service of a basic call in IP network, plus additional types of service. At the same time interfaces allow to integrate it both with fixed, and with mobile networks and switches. As a result the platform – a basis for convergence of networks mobile, fixed and IP communications at the level of switching, providing services and billing. The second important point is that RTU completely modular product. Thanks to a different configuration of modules it is possible to receive absolutely different solutions. Any monolithic solution acquires over time excess functionality which negatively affects quality of work and resource intensity in general. The solution consisting of separate components differs in bigger flexibility. For example, the developer company of the solution can place the RTU components on different servers and if necessary take different places to them. Reliability and scalability of such solution it is incomparable above. Owing to the flexibility the RTU platform has a wide scope: it is SIP telephony, communication hubs of any level, the UPATS organization, including virtual, an opportunity to provide a broad spectrum of modern communication services, including in the SaaS model.

The RTU platform is included in the Unified register of the Russian computer programs of Ministry of Communications and recommended for purchases by state structures.
