What is termination?

The process of call termination is opposite to the process of origination. Origination is the initiation of a call, which occurs as follows: • The caller dials the number and presses the "Call" button • The telephone company directs the call to the recipient’s provider Then, the termination process (the process of receiving the call) begins: • The recipient’s provider transmits the call to the recipient's phone and the phone starts ringing • The recipient picks up the phone and the conversation begins

The ANTRAX system is a unique solution for termination of voice traffic in GSM provider’s network.
You can get more information about it on the “Product” page.

ANTRAX is a unique solution for termination of voice traffic in GSM networks.

The system is simple, easy to operate and convenient. These features allow you significantly reduce time required for installation, configuration, monitoring and maintenance. They also help you to improve security and increase profits.

The elements of the ANTRAX system

Elements of the system are divided into two groups: Hardware and software.
Hardware includes: 1) Bearing block; 2) SIM card; and 3) GSM card.
Software modules are: 1) SIM server and 2) graphical user interface.

1. The bearing block has 15 slots for GSM and SIM boards.
2. SIM-board has 20 interfaces for SIM cards.
3. GSM board has 2 voice ports, channels.
4. SIM-server contains a database and a set of business logistics for management of
hardware elements.
5. Graphical user interface is a single point for management and
monitoring the system.

Convergence of VOIP and GSM networks
Interaction schematic of elements
of the ANTRAX system

GSM boards don't require SIM cards. All SIM cards are at IP network distance from GSM gateways—all in one place. It’s very profitable, convenient and safe. Currently this is the only way to resist ANTI FRAUD systems of GSM operators.

GSM operators employ ANTI FRAUD systems and mechanisms that help them to identify and block those SIM cards used for termination purposes within the network.
ANTRAX system imitates live subscriber behavior: thus avoiding blocking.


Scalability and flexibility

The Antrax system has a “building block” type design. To increase its productivity, simply add a new module or block. You can either begin a project or learn the system by buying a minimum kit: a bearing block and two boards (GSM and SIM).


Thanks to Radvision’s H323 stack, you won’t have compatibility issues with other manufacture’s equipment.

Guarantee of quality

The Antrax system is certified by the leading German concern TUV Rheinland Group. The system has following certificates:
CB: HU-000750
IECEE: HU-000751
EMC: M5 69240719 001
LVD: M1 69240718 0001

We also expect certificates from the FCC and UkrSEPRO.


Configuration, monitoring and management of the Antrax system is performed by a user-friendly graphic interface.

Single scheme (Stand Alone) is the simplest and most affordable solution. It consists of GSM and SIM boards installed into one bearing block in one location. In other words, it is a well-known GSM gateway with the SIM matrix. It is used to test the business models and system functions and is a good option to start with!
Diversified scheme: GSM and SIM boards are installed in individual bearing blocks at different locations. It solves the issue of ANTI FRAUD systems used by operators who try to imitate live subscriber’s behavior. It increases the security and reduces the risks; thus, increasing profits and saving money on support. It is a perfect solution for termination of large volumes of voice traffic.

Key features

  • Design
    Designed specifically for voice traffic termination in GSM network.
    The system was designed specifically for voice traffic termination in GSM network. It was not transferred from the corporate sector, therefore, it doesn’t require any extra settings and it’s easy to operate.
  • Architecture
    The system consists of three fully interoperable hardware elements. It allows you to use ANTRAX either as a simple GSM VOIP gateway or as a connection point between several GSM VOIP gateways with SIM server.
  • Scalability and flexibility
    The system allows you to increase the capacity by adding new elements. You won’t need to exchange current equipment and purchase new more expensive modules.
  • Control
    All configurations and control come from the graphical interface. You can use it with Windows, Linux or your Mac. The interface is easy to use, the usual operations run faster and "cheaper" (please refer Video)
    Termination of voice traffic is a very profitable business. Many GSM operators consider it fraud, so they use ANTI FRAUD tools that will prevent you from doing it. System ANTRAX has a set of business scripts that allows you to sound like a live subscriber. Therefore it makes it more difficult to detect the termination of traffic in network.
  • Price
    The ANTRAX system was developed in Central Europe, and you will be pleasantly surprised by its price because its development and IT support is much cheaper in this region.
