In fact, modern businesses of all scales and sizes prefer VoIP based services over traditional phone systems.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The reason is quite simple\u2014 Being able to<\/span><span style=\"font-weight: 400;\"> leverage capabilities such as auto-attendants, call routing, call forwarding, DND, Interactive Voice Response (IVR) systems, etc. without any extravagant expenses.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">These features boost productivity by allowing agents to answer calls from anywhere using their personal devices and the Internet. Thus, they are well-suited for both in-office and remote working models.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">VoIP solutions are a no-brainer for businesses, but they have their own set of limitations. The good news is that your provider can solve these issues for you, and you won\u2019t need to hire a support team.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This blog shares the seven most common VoIP problems and ways you can fix them.\u00a0<\/span><\/p>\n<h2>Network and LAN issues<\/h2>\n<p><span style=\"font-weight: 400;\">This is one of the most common problems that can arise while using <a href=\"https:\/\/www.acefone.com\/solutions\/voip-phone-service\/\">VoIP solutions<\/a>.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Network issues involve problems between personal computers or the equipment (such as router or modem) that connects them with the Internet. For instance, the router could be incompatible or malfunctioning.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For efficient VoIP performance, you need a router that prioritizes calls over less critical network traffic. This method of prioritizing network traffic is also known as Quality of Service or QoS.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">How to fix these network issues?<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Reset your router and computer to check the wiring.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Upgrade your router.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Make sure you configure your router for VoIP prioritization.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Try disabling the SIP application layer gateway.<\/span><\/li>\n<\/ul>\n<h2>Choppy audio<\/h2>\n<p><span style=\"font-weight: 400;\">A choppy audio call refers to a broken voice or missing words when both parties connect on a call.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The most common reason behind choppy audio is packet loss and insufficient bandwidth.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">It doesn\u2019t necessarily mean you have a slow Internet connection or there is too much network traffic.
