The modern mobile infrastructure, <strong>4G and 5G,<\/strong> relies on VoIP for voice transmission.&nbsp;<\/p>\n\n\n\n<p>Since 1995, VoIP started replacing POTS (Plain Old Telephone Service), popularly known as PSTN (Public Switched Telephone Network). The traditional telephone system was complex to set up and slow, as they used copper wires, and the signals were analog.&nbsp;<\/p>\n\n\n\n<p>VoIP does not need any such physical infrastructure for voice transmission. Above this, VoIP supports <a href=\"https:\/\/www.mirrorfly.com\/docs\/\">multiple forms of communication<\/a>, including SMS, fax, and voice messaging, in contrast to traditional telephones that could only enable phone calls.&nbsp;<\/p>\n\n\n\n<p>On the other hand, businesses will only need an app (softphone) like Google Voice, Microsoft Teams, Skype, or Viber installed on their systems to enable voice communication across their organisation.&nbsp;<\/p>\n\n\n\n<p>Apparently, there\u2019s no need to discard their traditional phones; rather, connect them to the internet using an adapter and convert them into VoIP phones (hardphones).&nbsp;<\/p>\n\n\n\n<p>However, in some cases, the apps might not always be convenient and secure in a business setting, and that\u2019s one reason why 53% of them, like yours, are<a href=\"https:\/\/www.contus.com\/blog\/how-to-build-a-voice-chat-app\/\" class=\"broken_link\"> building their own custom-built voice calling apps<\/a>.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Case_Study_Utah_State_Universitys_VoIP_Transformation\"><\/span><strong>Case Study: Utah State University\u2019s VoIP Transformation<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><strong>Challenge:<\/strong><\/p>\n\n\n\n<p>Utah State University faced high costs and inefficiencies with its traditional analogue phone system.
