A session border controller (SBC) is a unique piece of technology that helps make and protect important parts of a business’s communications infrastructure. It normally controls networks by either accepting or rejecting communications. It also controls communications between a small group of end devices on the network, which are called sessions. To finish this session, the session border manager is in charge of the border, which is where traffic moves from one network to another. Businesses and service providers can use SBCs as much as they want because they work well in networks.
The task of the session border controller
AudioCodes’ session border controller does the following:
Giving people access to SIP trunking
AudioCodes’ session boundary controller is an important part of any SIP trunking system. The SBC’s job is to keep an eye on all sessions that go back and forth between the company network and the ITSP network. The SBC not only decides how important a session is in case the network is busy, but it also decides where the session should go. Based on how the network is being used and the rules that have been set, it also decides how much data each session needs. In this way, it is possible to say that the SBC continues to work with SIP. It lets devices that use different forms of SIP talk to each other quickly and easily.
Protection and security for networks
The SBC’s main job is to protect and secure the network. To get rid of denial-of-service attacks, toll fraud, and fake attacks, it was built from the ground up. It also helps to protect the network by hiding the design. This makes it harder for crooks to get into the network’s weak spots. On top of that, the SBC allows encryption, which protects conversations from being illegally listened in on or changed.
Being a traffic cop for a while
The SBC basically keeps the VoIP network of a business or service network provider safe. While doing this job, it keeps control of session entries. A session entry control decides who can connect to the network. With this in mind, the SBC is the network’s guardian. It keeps the order and safety of the VoIP roads this way. The SBC makes and checks three lists: greylists, blacklists, and whitelists.
Cover your structure and translate your protocols.
When the session border controller is used to connect and integrate different protocols and networks that use them, everything works perfectly every time. The SBC changes between the different SIP versions. Because of this, calls go through all of them without any problems. Different VoIP solutions use different audio codecs that aren’t fully supported on both ends of a call. This is why the SBC changes protocols without warning. This is why the SBC was created: to get rid of many things. Try the best choices and methods to get the most out of them.
