SBC, also known as Session Border Controller, is a controller that regulates the calls in IP telephony at the demarcation point of a network. Asterisk SBC is one of the leading SBC solutions that can be implemented in a variety of diversified network designs.

Asterisk SBCs are leaders in this technology, and they ensure the maximum service quality with optimized resources to support VOIP service providers.

How does Session Border Controller work?

Session border controller is installed on the border point of the network, and it is used to hide IP communication signals. It provides features such as security, QoS, and multi-vendor support.

SBCs are deployed into the signaling and media paths between source and destination in a VoIP call. They use the Session Initiation Protocol (SIP) and media gateway control protocol.

Most importantly, SBC can control a communication session very deeply. So, it can provide security to a core SIP network and an application server. It provides client-to-server interoperability by performing the role of a back-to-back user agent.

It effectively ends each session and then restarts the session back and does the same operation. It works as a user agent client and user agent server both for each signaling message on every call session.

SBCs take complete responsibility for providing support for open source solutions for different types of infrastructure. They are capable of delivering multiple advanced SBCs functions on various network platforms and environments.

SBC allows the VOIP providers to administrate the calls on their networks and manage protocol syntax to achieve interoperability. They resolve the issues occurring from firewalls and network address translators in the network.
