In the wake of the development of network technologies, more and more companies and consumers are moving to unified communications, which allows them to save money on IT telephony and cloud services, as well as to optimize and balance network traffic and much more. Along with the advantages of introducing and using IT telephony, there are also risks associated with cyber-attacks and various external information threats.
To protect IP telephony from unauthorized access, cyber attacks and various external threats, it is necessary to install a Session Border Controller (SBC) at the network border, because the Firewall used in the local network infrastructure can not provide protection for voice traffic and IP telephony.
Key Features of SBC (Session Border Controller):
- Cover the internal local area network topology;
- Provide protection against cyber attacks and unauthorized access;
- Divide internal and external networks at the level of physical interfaces, including the distribution of traffic on different physical interfaces;
- Convert signal protocols (for example, convert H.323 to SIP), as well as convert voice data from one codec to another;
- Routing of voice traffic, re-routing and prioritization;
- Set restrictions (number of sessions, lane bar and other settings);
- REST, WebRTC support;
- Conversation recording (SIPREC);
- Collection and storage of billing information (CDR).
