OREANDA-NEWS. August 07, 2013. Beltelecom, being the largest operator of telecommunication services in Belarus, performs daily monitoring of the security status of communication networks to protect its subscribers from fraud.

Beltelecom warns: when receiving calls from abroad, the unknown Belarusian number is displayed or there is no information about the incoming call and the quality of connection is unsatisfactory, the subscriber deals with illegal termination of telephone voice traffic.

In this case the connections go through the Internet network and then they are transferred to the public telephone network. For this purpose a special equipment, so called "voice gateways", is used. They make it possible to initiate a phone call on the Internet network, transfer it at a distance and accept in any point of telephone network. 

In July, 2013 Beltelecom launched an antifraud system on the basis of equipment and software of cVidya company (Israel) (fraud is a type of fraudulent activity in the field of information technologies, in particular, unauthorized actions and illegal use of resources and services in communication networks).  This system allows, in particular, to fight against such type of fraudulent activity as illegal IP-telephony. 

Distinguishing feature of the equipment is the possibility to reveal fraudulent operations in real-time mode, using data at the level of exchange of signaling information between exchanges. The purchased software enables to analyze the behavior of a subscriber during different periods of time. Data on illegal use of services, received from the anti-fraud system, are transferred to the law enforcement authorities to take measures of administrative and criminal liability.
