VoIP telephony has proven to be the most innovative and efficient solution for managing business communications. It offers numerous benefits for managing incoming and outgoing calls, which is why many organizations are opting to modernize their women database communications platforms with cloud telephony. If this is the case for your company, you should know that you’ll need a Session Border Controller to keep everything running securely.
The SBC, or session border controller, is a key element in regulating and protecting IP communication flows. A border controller should be deployed at the edges of a VoIP network and is currently used to enhance various forms of real-time communication.
In the following lines, we explain what an SBC is, how it works, and what its functions are.
What is an SBC or Session Border Contr?
A Session Border Controller (SBC) is a network device used to secure and manage voice and video communications on an Internet Protocol (IP) communications network. It provides security, quality of service (QoS) control, session switching, and protocol address translation (PAT) functions. This enables better interoperability between different communications technologies and more efficient management of voice and video communications on a network.
One of the essential components for to be secure and operational , meeting the standards required by the most competitive companies, is the SBC .
Today, companies using an SBC can connect and control traffic and media services transmitted from corporate VoIP networks to the public internet, as well as from other private IP networks and other backbone service provider networks.
With SIP trunks, the Session Border Controller controls communication between the public telephone network and cloud-hosted services. The device also serves to strengthen the interconnection of legacy PBX systems, on-premises systems, Microsoft Teams, and other contact center environments.
Session Border Controller Types
Because the requirements and scalability of VoIP telephony for an organization are often very diverse, SBC product manufacturers offer a very wide range of these devices.
- Software-based SBC appliances that are hosted and run on virtualized servers, enabling NFV network functions virtualization.
- Session border controller applications for SIP trunking. These are deployed at the edge of the enterprise network to act as a demarcation point.
- SBC with SIP trunking on enterprise premises, but the vendor retains ownership and management of the device.
- SBC device as a virtual appliance running from the provider’s network.
- SBC at the edge of the corporate IP network for routing calls through IP contact networks.
- SBC for cloud IP telephony communications services.
- SBCs implemented at Internet borders to extend communication services for mobile workers, teleworkers, and small offices.
- Devices for unifying disparate or fragmented communication environments, which are compos of PBX, UC or other integrat systems.
- SBC for core network boundary control, access to customer-oriented services, and connections to legacy networks.
