Hosted VoIP Service for Startups<\/a><\/li><\/ul><\/li><\/ul><\/nav><\/div>\n<h2><span class=\"ez-toc-section\" id=\"What_is_a_Class_4_Softswitch\"><\/span>What is a Class 4 Softswitch?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Softswitch is one of the key components for a wholesale VoIP business.\u00a0 Basically, it\u2019s a server-side software that enables you to connect one phone line to another through the Internet.\u00a0 To put it more simply, it\u2019s a software that makes IP to IP calls.\u00a0 A server needs to be deployed for softswitch functionality.\u00a0 <\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Choose_the_Best_Softswitch_Vendors\"><\/span>Choose the Best Softswitch Vendors<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Choosing the best softswitch is necessary for optimum business performance.\u00a0<\/span><span style=\"font-weight: 400;\">You should consider the following features of class 4 softswitch while selecting from the best softswitch vendors :<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Billing_Management\"><\/span>Billing Management<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Choose a softswitch with an integrated billing system. Separated <\/span><a href=\"https:\/\/www.revesoft.com\/products\/itel-billing\"><span style=\"font-weight: 400;\">VoIP billing systems<\/span><\/a><span style=\"font-weight: 400;\"> might get you in trouble like compatibility issues and lack of functionality. An integrated billing feature will give you precise control over the business. Keep in mind that unbilled call minutes bring significant loss to your VoIP business and should be prevented by any means. The billing system should also be scalable, automatic and multi-currency enabled. Check out for features like automatic invoice generation, report generation ability, call statistics or diagram. These enable you to monitor and control your service better.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Routing\"><\/span>Routing<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">How good is the routing function? To ensure cost-saving routing, it is necessary to buy routes from termination providers throughout the world. Having a wider range of routes ensures smooth business operation with maximum profit. Look for the Least-Cost Routing (LCR) function in the switch. LCR enables a softswitch to determine which outbound line will be least expensive. Percentage routing is another important feature you should look for. It allows a softswitch to transmit the call through a route that has a maximum percentage and if not available, choose the next maximum percentage. Longest Prefix Match feature matches the incoming call\u2019s prefix with the prefix assigned to each route and selects the route with which the call has a maximum match. An automatic blockage of unprofitable calls is another feature you don\u2019t want to miss. <\/span><b>\u00a0<\/b><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Secured_Switching_Function\"><\/span>Secured Switching Function<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Class 4 softswitch should be a stable and secure system ensuring efficient data (Voice and SMS) transmission. \u00a0 In order to obtain better security, the switch should have VPN support and Network Topology Hiding. Using VPN means the client has to go through the VPN server (VPN is the middleman here) and encrypt\/decrypt data before channeling it to the softswitch. Make sure that the VPN server and the softswitch server is the same data center.\u00a0 This will avoid latency and poor voice quality. Topology hiding is a feature that assures enhanced SIP network security.\u00a0 Normally, critical IP address data is sent to other networks in regular SIP traffic. Topology hiding prevents third party threats from stealing this data and attacking your SIP network.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Sales_and_Analysis_Report\"><\/span>Sales and Analysis Report<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The ability to generate on demand report, Inbound\/Outbound\/Unauthorized call report, traffic volume tracking and revenue report help you to keep track of your business performance and accelerate business development. Having all the numbers figured out gives you the leverage to measure your business parameters and take the right business decision.\u00a0 Also, look for softswitch vendors that offer Payment and Sales report, data export in XML and CSV format.<\/span><b>\u00a0<\/b><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Flexibility_and_Compatibility\"><\/span>Flexibility and Compatibility<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Check out protocols and codecs compatibility before you buy your softswitch. Make sure your supplier and clients are using codecs that are supported by your softswtich. If your switch has transcoding option then protocols and codecs can be converted in the desired format. A dual-layer firewall should also be considered.\u00a0\u00a0<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Easy_and_Quick_Set_Up\"><\/span>Easy and Quick Set Up<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Make sure that the softswitch set up is easy and fast. It will help you in quickly getting started with your VoIP business. Look for a user-friendly and robust management portal where all the activities can be managed which will ultimately result in better customer satisfaction, loyalty and retention. All these factors are extremely important for the success of a business.\u00a0<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Post_Sale_Support\"><\/span>Post Sale Support<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">It is obvious that majority of the softswitch vendors will provide technical support during the whole purchasing journey, but what after that? You must have chosen the best softswitch as per your needs, but eventually you will need technical support for troubleshooting and various other tasks. Ensure that your service provider offers on-demand troubleshooting at any given time. Not only it saves you from the hassle of paying extra money for support but also lets you focus on your important business activities.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Regular_Updates_and_Upgrades\"><\/span>Regular Updates and Upgrades<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Market Landscape is never constant. Even after you purchase the best softswitch, it is crucial to make\u00a0it adaptable\u00a0\u00a0in accordance with the ongoing trends. You will need to match your softswitch services with your competitors or even make it better than theirs. This means that regular updates are necessary to keep you ahead in the market.\u00a0 Check\u00a0which softswitch vendors\u00a0provide support with updates and upgrades and if those are free or paid. You can go with the paid ones if it is worth your business requirement.\u00a0<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Scalability\"><\/span>Scalability<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Lastly, avoid buying your softswitch based on only CC (concurrent calls) and CPS (calls per second) values. For example, while buying a house someone does not just look for a bigger space, right?\u00a0 Apart from spacing, there are other features to look for in a house. Same goes in case of a softswitch.\u00a0 CC and CPS are important but also look for features, functionality, integration and customization options.\u00a0\u00a0\u00a0<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Getting_Started\"><\/span>Getting Started<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">VoIP business is quite trending these days and is certainly profitable. You just need to be thoughtful and mindful. Before you choose the best from various softswitch vendors, make a checklist of the features you are looking for in your softswitch that serves your business best.\u00a0 Choosing the best <\/span><a href=\"https:\/\/www.revesoft.com\/products\/hosted-voip-softswitch\"><span style=\"font-weight: 400;\">VoIP Softswitch<\/span><\/a><span style=\"font-weight: 400;\"> will ensure maximum profit and seamless business experience for you and your clients.<\/span><\/p>\n<p style=\"text-align: center;\"><a class=\"btn btn-primary\" style=\"padding: 8px 12px; font-size: 18px;\" href=\"https:\/\/www.revesoft.com\/demo-request\/\" target=\"_blank\" rel=\"noopener\">Contact for Free Demo<\/a><\/p>\n<h2 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"Read_Also\"><\/span><strong>Read Also<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"The_Difference_Between_Class_4_and_Class_5_Softswitch\"><\/span><a href=\"https:\/\/www.revesoft.com\/blog\/softswitch\/class-4-vs-class-5-softswitch\/\" target=\"_blank\" rel=\"noopener\">The Difference Between Class 4 and Class 5 Softswitch<\/a><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<h3 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"7_Benefits_of_Hosted_VoIP_Service_for_Startups\"><\/span><a href=\"https:\/\/www.revesoft.com\/blog\/softswitch\/benefits-hosted-voip-service\/\" target=\"_blank\" rel=\"noopener\">7 Benefits of Hosted VoIP Service for Startups<\/a><span class=\"ez-toc-section-end\"><\/span><\/h3>\n","protected":false},"excerpt":{"rendered":"<p>According to Grand View Research, the global mobile VoIP market size is expected to reach USD 145.76 billion by 2024.\u00a0 The expansion of this market is driven by technological leap and increased usage of the new services over various channels.\u00a0 Robust growth in the VoIP market depicts the importance and demand for VOIP business solutions.
