3CX reengineered their OS from the “ground up” to implement current and future security enhancements, increase scalability and launch new enhancements. 3CX Call Manager was no exception– boasting an entirely new Call Manager based on the experience of 15 years and 350,000+ installations. Completely rewritten to focus on larger installs, the new Call Manager handles more calls and offers better performance, as well as diversion header support. Group SMS, a popular feature request, is now included as well! We’ve included just some of the new Call Manager features below, with additional updates happening under the hood.
