3CX Version 20 is the latest release, bringing significant changes to business telephony. After more than 2 years of development, this version has been thoroughly re-engineered, setting the foundation for the future of communications.
Here are the key points of 3CX V20:
Strengthened Security:
3CX is taking decisive steps to improve security and reduce the risk of future attacks.
The measures involve:
- Network updates,
- an isolated build environment
- new EDR monitoring tools
- 24/7 monitoring by threat hunting specialists
- and stricter access control policies.
Working with Mandiant (a well-known US cyber security company, part of Google), 3CX Version 20 applies the Remediation Plan Recommendations to strengthen network security.
Additional security features include password hashing, removal of passwords from welcome emails, IP-based lockdown on the Web Client, and 2FA for non-SSO installations.
The Linux edition now runs on Debian 12, and 2FA is available alongside Microsoft and Google SSO.
SIP management updates
Over 20 years, 3CX has made significant progress, but 3CX’s commitment to the telephone remains steadfast, and so is yours! With V20, 3CX has updated its Call Manager to deliver unmatched call center features both now and in the future.
3CX has introduced additional queue strategies, including targeting agents with the most calls, as well as improved barge-in and pickup capabilities for call center supervisors. Queues are now programmable, empowering users to build custom call center applications with scripting knowledge. In addition, 3CX has upgraded its reporting engine to not only refine existing reports but also integrate seamlessly with leading reporting and dashboard applications such as Grafana. 3CX has also introduced more robust telephony features such as transfer-back-on-busy. Finally, 3CX has launched a powerful API that lets companies build telephony applications with ease.
A unified client and Admin Console reduce the attack surface for hackers.
Audited by Mandiant, Reversinglabs, Coverity, and Kaspersky, 3CX V20 is the most secure communication solution on the market.
Contact Center Improvements:
Without a doubt, AI represents a transformative force in communication systems. In V20, 3CX has started laying the groundwork for seamless AI integration. Starting with recording transcription already integrated with Google Voice, 3CX has developed the ability to not only transcribe calls but also analyze them and generate reports based on those calls. This is an area ready for significant development in the coming months.
