3CX Releases v20 Update Focusing on CRM Integration Fixes

On September 30, 2026, 3CX, a developer of cloud and on-premise telephony solutions, released the v20 update for its platform. The key focus of this release was fixing bugs and stabilizing CRM integration modules. The update aims to address technical shortcomings that affected the interaction between telephony systems and client databases.

In addition to optimizing CRM connectivity, the developers updated user authentication mechanisms and configuration templates. These fixes resolve glitches that could previously occur during incoming call processing and data routing between the IP-PBX and external systems. The stabilization of these modules prevents broken conversation histories and ensures continuous communication tracking.

For businesses, this means improved reliability for sales teams and contact centers when handling calls. The proper functioning of the updated modules prevents the loss of client cards, guarantees accurate caller data display at the time of the call, and ensures stable automatic call recording for further analysis.
