What is one benefit of using a Session Border Controller (SBC)?

A Session Border Controller (SBC) plays a significant role in managing and securing Voice over IP (VoIP) communications, and one of its key benefits is the ability to help hide IP addressing schemes. By acting as an intermediary between endpoints in a VoIP network, the SBC can obscure the internal IP addresses of those endpoints from external entities. This is crucial for enhancing the security of the network, as it makes it more difficult for potential attackers to target specific devices or exploit vulnerabilities related to real IP addresses.

Hiding IP addresses can also help in preventing direct attacks and exposing less information about the internal network architecture. In environments where there is a need for confidentiality, such as in enterprise or service provider networks, utilizing an SBC to mask IP addressing schemes becomes a vital protective measure.

Other options, while they may seem relevant, either do not directly relate to the core functions of an SBC or are not guaranteed outcomes of its deployment. For instance, enhancing web browsing speeds and managing mobile data services are outside the typical responsibilities of Session Border Controllers. Additionally, while SBCs can enhance call quality through various mean adjustments, they do not necessarily guarantee improved audio quality as a fundamental feature.
