It runs independently of the browser, sits in your system tray, and is available the moment you need it \u2014 without switching tabs or opening a window. For anyone who spends most of their day on a single machine, the desktop app is the right choice.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"2298\" height=\"1944\" src=\"\/kb\/wp-content\/uploads\/2026\/04\/Desktop_sample.webp\" alt=\"Siperb desktop softphone making an active voice call on macOS\" class=\"wp-image-13615\"\/><figcaption class=\"wp-element-caption\">Siperb desktop \u2014 making a call on macOS<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Always on, always ready<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The desktop app is a persistent application \u2014 it keeps running whether your browser is open or not. Close Chrome to free up memory, restart it for an update, or switch browsers entirely: your phone stays registered and calls keep coming through. No tabs to pin, no session to lose, no call missed because the browser was in the middle of a restart.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Session security<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The browser phone keeps you signed in using cookies \u2014 a mechanism that works well but has known attack surfaces (session hijacking, cross-site exposure, browser data access). The desktop app stores your session credentials in encrypted storage on disk. The data is tied to the application and the device, not to a browser profile that can be copied or exported.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Direct PBX connection over UDP, TCP, or TLS<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This is the capability that sets the desktop app apart entirely. Only the desktop app supports native SIP transport &#8212; UDP, TCP, and TLS &#8212; which means it can register directly with a PBX on your local network, with no internet connection and without routing anything through Siperb&#8217;s infrastructure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In practice this means:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>On-premises only<\/strong> &#8212; connect to an Asterisk or FreePBX server on your LAN without exposing it to the internet<\/li>\n\n\n\n<li><strong>Air-gapped environments<\/strong> &#8212; works on networks with no external internet access at all<\/li>\n\n\n\n<li><strong>TLS transport<\/strong> &#8212; encrypted SIP signalling directly between the app and your PBX, without a proxy in the path<\/li>\n\n\n\n<li><strong>Zero dependency on Siperb<\/strong> &#8212; the app becomes a fully self-contained SIP client<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-hb-message is-style-info wp-block-hb-message--withicon wp-block-paragraph\">Direct transport (UDP\/TCP\/TLS) is configured under <strong>Registration Mode<\/strong> in the connection settings. See <a href=\"\/kb\/registration-modes\/\">Registration Modes &#8594;<\/a> for the full comparison.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"wp-rich-text-font-awesome-icon
