SP4 – More Features Plus Linux Edition is RC

3CX on Linux Release CandidateService Pack 4 is here in time for the holidays and it’s packed with new features and improvements. The V15 Linux edition is now a release candidate. We added a DECT / FXS provisioning feature that allows you to easily provision a DECT base station and assign handsets to individual extensions. Furthermore, a new reporting module and many fixes to the reports.
