So, what makes FreeSWITCH 18 tick? Here are some of the key features and improvements you can expect:
FreeSWITCH was created in 2006 to bridge the gap between traditional proprietary hardware PBX systems and emerging software-defined networks. Unlike some of its contemporaries, FreeSWITCH was built from the ground up to take full advantage of modern multi-core processor architectures, ensuring thread safety and high concurrency. Key Enhancements in the 1.8 Release Branch freeswitch 18 pdf
FreeSWITCH 1.8 is a cornerstone release in the world of open-source software-defined telephony. Built to handle voice, video, and text, this robust platform powers everything from small business private branch exchanges (PBXs) to massive carrier-grade communication networks.
FreeSWITCH loads a single master XML document at startup. This document is dynamically constructed by parsing /etc/freeswitch/freeswitch.xml , which includes other configuration blocks via X-PRE-PROCESS tags.
While pre-compiled packages exist, compiling from source ensures you have absolute control over the active modules. First, a vital clarification for new users: typically
In addition to the key features mentioned above, FreeSWITCH 18 also includes a range of new features and improvements, including:
Stop hardcoding your users and dialplans into local XML files. By utilizing mod_xml_curl , you can instruct FreeSWITCH to request dialplans, directories, and configurations directly from an external web server or database in real-time.
Upgraded OpenSSL integration, fixing vulnerabilities and enabling secure SIP (SIPS) and SRTP out of the box. Loading Modules So, what makes FreeSWITCH 18 tick
Every action inside FreeSWITCH—such as a channel being created, a DTMF key being pressed, or a call hanging up—triggers an internal event. The central event system broadcasts these messages globally, allowing internal modules or external applications to subscribe to and act upon specific system states. Modular Architecture
Because FreeSWITCH platforms are frequent targets for toll-fraud scanners, robust security is paramount:
