That core ships in three distinct forms depending on who you are and what you&#8217;re building.<\/p>\n\n\n\n<p>This knowledge base is organised around those three products.

Drop it into your website, CRM, SaaS platform, or internal tool and your users get a fully functional SIP softphone running directly in the browser. No Siperb account required to get started. No branding you didn&#8217;t choose. Just a phone that works.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignleft size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"230\" height=\"149\" src=\"\/kb\/wp-content\/uploads\/2026\/04\/Layers_side.webp\" alt=\"\" class=\"wp-image-13577\"\/><\/figure>\n<\/div>\n\n\n<p>The SDK handles SIP signalling over WebSocket, WebRTC media negotiation, and the phone UI \u2014 delivered as a single JavaScript file you load from a CDN or self-host. You choose how deep you integrate:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Manual setup<\/strong> \u2014 hard-code your PBX credentials, zero cloud dependency, completely free<\/li>\n\n\n\n<li><strong>Siperb provisioning<\/strong> \u2014 manage SIP credentials centrally, deploy across users without touching code<\/li>\n\n\n\n<li><strong>Siperb proxy<\/strong> \u2014 route calls through Siperb&#8217;s secure media proxy; no exposed passwords, transcoding support, SIP trace logs<\/li>\n<\/ul>\n\n\n\n<p>The core SDK and Browser Phone UI are open source and free to use. The provisioning service and proxy are free on the Personal plan. Transcoding, extended logs, and multi-user deployments require a paid plan.<\/p>\n\n\n\n<p><strong>Start here:<\/strong> <a href=\"\/kb\/web-phone-for-developers\/\">Web Phone for Developers \u2192<\/a><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\"><a href=\"\/kb\/siperb-softphone-overview\/\">Siperb Softphone \u2014 For End Users<\/a><\/h2>\n\n\n\n<p><strong>You want a ready-made softphone that connects to your existing PBX.<\/strong><\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignleft size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"230\" height=\"127\" src=\"\/kb\/wp-content\/uploads\/2026\/04\/Softphone_side.webp\" alt=\"\" class=\"wp-image-13578\"\/><\/figure>\n<\/div>\n\n\n<p>Siperb Softphone is the full end-user application \u2014 available as a web app, a desktop application for Windows, macOS, and Linux, and a mobile app for iOS and Android. All three share the same account, call history, contacts, and settings.<\/p>\n\n\n\n<p>The critical concept for anyone deploying Siperb Softphone is <strong>Registration Mode<\/strong> \u2014 it determines how the phone connects to your PBX and what features are available:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Proxy mode<\/strong> (default) \u2014 devices register through Siperb&#8217;s secure SIP proxy. Your PBX doesn&#8217;t need to be WebRTC-enabled. Enables push notifications, transcoding, SIP trace logs, and call recording storage. Requires a Siperb account.<\/li>\n\n\n\n<li><strong>WebSocket mode<\/strong> \u2014 the phone connects directly to your PBX over WebSocket. Your PBX must support WebRTC natively. No Siperb involvement in the call path. Available on all plans including free.<\/li>\n<\/ul>\n\n\n\n<p>If your PBX already supports WebRTC (Asterisk with <code>pjsip<\/code>, FreeSWITCH, OpenSIPS), WebSocket mode gets you running in minutes. If it doesn&#8217;t \u2014 or if you want the full feature set \u2014 Proxy mode is the right choice.<\/p>\n\n\n\n<p>The Personal plan is free and includes proxy access, provisioning, push notifications, and community support. Business and Business Pro plans unlock multi-user domain management, extended log retention, technical support, and transcoding.<\/p>\n\n\n\n<p><strong>Start here:<\/strong> <a href=\"\/kb\/siperb-softphone-overview\/\">Siperb Softphone Overview \u2192<\/a><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\"><a href=\"\/kb\/co-branded-softphone\/\">Co-branded Softphone \u2014 For MSP&#8217;s &amp; Resellers<\/a><\/h2>\n\n\n\n<p><strong>You want to offer a softphone under your own brand.<\/strong><\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignleft size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"230\" height=\"260\" src=\"\/kb\/wp-content\/uploads\/2026\/04\/Co_branding-1.webp\" alt=\"\" class=\"wp-image-13580\"\/><\/figure>\n<\/div>\n\n\n<p>The Co-branded Softphone is the same application as Siperb Softphone \u2014 identical features, identical platforms \u2014 but presented entirely under your organisation&#8217;s identity.
