This version brings numerous functional and technical improvements designed to simplify administration and enhance the user experience.<\/p>\n<img decoding=\"async\" class=\"alignnone wp-image-16525 size-full\" src=\"https:\/\/www.linphone.org\/wp-content\/uploads\/2025\/04\/4.png\" alt=\"\" width=\"1280\" height=\"370\" srcset=\"https:\/\/linphone.gtec.pro\/wp-content\/uploads\/2025\/04\/4.png 1280w, https:\/\/linphone.gtec.pro\/wp-content\/uploads\/2025\/04\/4-500x145.png 500w, https:\/\/linphone.gtec.pro\/wp-content\/uploads\/2025\/04\/4-1024x296.png 1024w, https:\/\/linphone.gtec.pro\/wp-content\/uploads\/2025\/04\/4-768x222.png 768w\" sizes=\"(max-width: 1280px) 100vw, 1280px\" \/>\n<h2>Bidirectional Calling with Third-Party Domains<\/h2>\n<p>The SIP Bridge (B2BUA) has evolved and now supports incoming calls from external domains such as third-party SIP domains, PSTN networks, or virtual numbers \u2014 in addition to already supporting outgoing calls. Thanks to this update, calls between Flexisip and third-party domains can now flow in both directions (incoming and outgoing).<br \/>\nUser account management has also been optimized: the B2BUA can now dynamically retrieve gateway accounts from a database, replacing the old method of using text file configuration.<\/p>\n<p>This feature allows integrators looking to connect external telephony services to their Flexisip infrastructure to maintain a clean, centralized architecture.<\/p>\n<p>\ud83d\udc49 <a href=\"https:\/\/wiki.linphone.org\/xwiki\/wiki\/public\/view\/Flexisip\/Configuration\/Back-to-back%20User%20Agent%20(b2bua)\/SIP%20Bridge\">Read the dedicated article for more information.<\/a><\/p>\n<h2>Proxy \/ NAT Helper: RFC 5626 Compliance<\/h2>\n<p>Flexisip introduces a <strong>new NAT routing strategy<\/strong> based on the <strong>flow-token<\/strong> <strong>mechanism<\/strong>, in compliance with <strong>RFC 5626<\/strong>.<br \/>\nThis improvement enables:<\/p>\n<ul>\n<li>Better handling of persistent connections;<\/li>\n<li>More reliable signaling through NAT routers;<\/li>\n<li>Increased compliance with modern SIP standards.<\/li>\n<\/ul>\n<p>\ud83d\udc49 <a href=\"https:\/\/datatracker.ietf.org\/doc\/html\/rfc5626\">Learn more about RFC 5626.<\/a><\/p>\n<h2>Time Unit Configuration<\/h2>\n<p>You can now <strong>specify a time unit (ms, s, min, h, d, m, y)<\/strong> for all duration-related parameters in the configuration file. No more manual unit conversions \u2014 you can now directly write values like `30min` or `1y`, reducing the risk of errors.<\/p>\n<h2>Improved RTP\/RTCP Port Management<\/h2>\n<p>The SIP Bridge (B2BUA) and conference servers now support new parameters (`audio` and `video port`) to precisely define the port ranges used for media traffic (RTP\/RTCP). This enhances firewall compatibility and simplifies deployment in secured environments.<\/p>\n<h2>Configurable Conference Duration<\/h2>\n<p>A new audio parameter allows setting a maximum duration for incoming calls on the conference server. This ensures that calls exceeding a certain time limit are automatically terminated.<\/p>\n<h2>New Supported Environment<\/h2>\n<p>Flexisip 2.4 is now compatible with <strong>Ubuntu 24.04<\/strong>, staying aligned with the latest Linux OS versions.<\/p>\n<p>&nbsp;<\/p>\n<table style=\"border-collapse: collapse; width: 100%;\">\n<tbody>\n<tr>\n<td style=\"width: 100%; text-align: center;\"><a href=\"https:\/\/gitlab.linphone.org\/BC\/public\/flexisip\"><strong>Visit the dedicated GitLab page.<\/strong><\/a><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"author":8,"featured_media":16513,"parent":0,"template":"","meta":{"_acf_changed":false,"inline_featured_image":false},"actualites-category":[39],"class_list":["post-16500","actualites","type-actualites","status-publish","has-post-thumbnail","hentry","actualites-category-release"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v25.3.1 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Flexisip 2.4 is now available!
