Others need to understand the terms sip and ip-telephony. What is the difference between them? Then it will become clear how everything works. The most common technology is IP-telephony. This protocol connected all the computer networks of the planet. That&#8217;s how the Internet appeared. That&#8217;s why all devices have a unique IP address. Voice over IP is a technology used to transmit audio information over a network. It allows you to make calls over the Internet, keep in touch during webinar broadcasts, etc. For newcomers sip sounds like a completely unfamiliar concept. However, it&#8217;s not all that complicated.\u00a0 SIP ip-telephony is one of the protocols. Simply put, IP in this comparison is a laptop and SIP is Acer.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"sip-telephony_what_it_is_and_how_it_works\"><\/span>SIP-telephony: what it is and how it works<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><a href=\"https:\/\/en.wikipedia.org\/wiki\/Session_Initiation_Protocol#:~:text=The%20Session%20Initiation%20Protocol%20(SIP,voice%2C%20video%20and%20messaging%20applications.\" target=\"_blank\" rel=\"nofollow\">SIP<\/a> is a communication tool that establishes a language between different devices for error-free communication. Some people mistakenly imagine it only with Internet calls (perhaps because sip with number substitution is one of the most popular variants of the protocol).<\/p>\n<p><img class=\"aligncenter\" src=\"https:\/\/blog.sms-man.ru\/wp-content\/uploads\/2021\/02\/main1.png\" alt=\"SIP-\u0442\u0435\u043b\u0435\u0444\u043e\u043d\u0438\u044f: \u0447\u0442\u043e \u044d\u0442\u043e \u0438 \u043a\u0430\u043a \u0440\u0430\u0431\u043e\u0442\u0430\u0435\u0442\" \/><\/p>\n<p>In fact, its application is much wider. It can be used for IP-telephony, audio and video conferences, etc. Connecting an sip-phone allows you to create a &#8220;client-server&#8221; scheme. The system will work in request-response mode. This protocol is available if the Internet speed is 64 Kbps or higher.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"what_is_good_about_sip_service_with_number_swapping?\"><\/span>What is good about SIP service with number swapping?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>It allows you to make outgoing calls and receive them using a virtual PBX:<\/p>\n<ul>\n<li>via PC or laptop (SIP-client required);<\/li>\n<li>via WI-fi or 3g\/4g with SIP programs installed on the mobile device;<\/li>\n<li>By connecting sip-phone to the router;<\/li>\n<li>By means of an telephone;<\/li>\n<li>SIP IP-telephony<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"the_essence_of_sip-telephony?\"><\/span>The essence of SIP-telephony?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A simple example is a call from a client on a computer, to a<a href=\"https:\/\/sms-man.com?ref=tsatsa\" target=\"_blank\"> company that uses SIP<\/a> with number substitution. First, the person&#8217;s voice is compressed into a digital signal by the codec. Then the signal is transmitted to the company. The devices &#8220;recognize&#8221; each other by the IP address. A sip communication session begins. Then the signal is converted back to voice.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"setting_up_a_sip_phone\"><\/span>Setting up a sip phone<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Before installing an sip-phone, you must do the following steps. The first step is to choose a quality product. Reliability of communication should be in the first place. The service should have available numbers of a suitable operator and the ability to configure the service.<\/p>\n<p>In addition, you need to be well prepared. You will need an Internet connection, a laptop, headphones and software to make calls. A useful bonus is a sip-format number. One question remains &#8211; how and who installs the sip-phone?<\/p>\n<p><strong>Two options are possible:<\/strong><\/p>\n<ul>\n<li>The company providing the virtual PBX service ;<\/li>\n<li>Self-configuration according to the manufacturer&#8217;s instructions.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Table of Contents: SIP-telephony: what it is and how it worksWhat is good about SIP service with number swapping?The essence of SIP-telephony?Setting up a sip&hellip;<\/p>\n<div class='heateorSssClear'><\/div><div  class='heateor_sss_sharing_container heateor_sss_horizontal_sharing' heateor-sss-data-href='https:\/\/sms-man.com\/blog\/sip-and-ip-telephony-what-is-the-difference\/'><div class='heateor_sss_sharing_title' style=\"font-weight:bold\" ><\/div><ul class=\"heateor_sss_sharing_ul\"><li class=\"heateorSssSharingRound\"><i style=\"width:80px;height:25px;border-radius:5px;\" alt=\"Facebook\" Title=\"Facebook\" class=\"heateorSssSharing heateorSssFacebookBackground\" onclick='heateorSssPopup(\"https:\/\/www.facebook.com\/sharer\/sharer.php?u=https%3A%2F%2Fsms-man.com%2Fblog%2Fsip-and-ip-telephony-what-is-the-difference%2F\")'><ss style=\"display:block;\" class=\"heateorSssSharingSvg heateorSssFacebookSvg\"><\/ss><\/i><\/li><li class=\"heateorSssSharingRound\"><i style=\"width:80px;height:25px;border-radius:5px;\" alt=\"Twitter\" Title=\"Twitter\" class=\"heateorSssSharing heateorSssTwitterBackground\" onclick='heateorSssPopup(\"http:\/\/twitter.com\/intent\/tweet?via=smsmantweets&text=SIP%20and%20IP-telephony%20-%20what%20is%20the%20difference%3F&url=https%3A%2F%2Fsms-man.com%2Fblog%2Fsip-and-ip-telephony-what-is-the-difference%2F\")'><ss style=\"display:block;\" class=\"heateorSssSharingSvg heateorSssTwitterSvg\"><\/ss><\/i><\/li><li class=\"heateorSssSharingRound\"><i style=\"width:80px;height:25px;border-radius:5px;\" alt=\"Telegram\" Title=\"Telegram\" class=\"heateorSssSharing heateorSssTelegramBackground\" onclick='heateorSssPopup(\"https:\/\/telegram.me\/share\/url?url=https%3A%2F%2Fsms-man.com%2Fblog%2Fsip-and-ip-telephony-what-is-the-difference%2F&text=SIP%20and%20IP-telephony%20-%20what%20is%20the%20difference%3F\")'><ss style=\"display:block;\" class=\"heateorSssSharingSvg heateorSssTelegramSvg\"><\/ss><\/i><\/li><li class=\"heateorSssSharingRound\"><i style=\"width:80px;height:25px;border-radius:5px;\" alt=\"Reddit\" Title=\"Reddit\" class=\"heateorSssSharing heateorSssRedditBackground\" onclick='heateorSssPopup(\"http:\/\/reddit.com\/submit?url=https%3A%2F%2Fsms-man.com%2Fblog%2Fsip-and-ip-telephony-what-is-the-difference%2F&title=SIP%20and%20IP-telephony%20-%20what%20is%20the%20difference%3F\")'><ss style=\"display:block;\" class=\"heateorSssSharingSvg heateorSssRedditSvg\"><\/ss><\/i><\/li><li class=\"heateorSssSharingRound\"><i style=\"width:80px;height:25px;border-radius:5px;\" alt=\"Pinterest\" Title=\"Pinterest\" class=\"heateorSssSharing heateorSssPinterestBackground\" onclick=\"javascript:void( (function() {var e=document.createElement('script' );e.setAttribute('type','text\/javascript' );e.setAttribute('charset','UTF-8' );e.setAttribute('src','\/\/assets.pinterest.com\/js\/pinmarklet.js?r='+Math.random()*99999999);document.body.appendChild(e)})());\"><ss style=\"display:block;\" class=\"heateorSssSharingSvg heateorSssPinterestSvg\"><\/ss><\/i><\/li><\/ul><div class=\"heateorSssClear\"><\/div><\/div><div class='heateorSssClear'><\/div>","protected":false},"author":9,"featured_media":2722,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[1],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v15.7 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>SIP and IP-telephony - what is the difference?
