Eventually, I have faced a new issue: on iOS 26.6 and 3CX 20.0.23.165, I can't attach any files (like PDFs) from "On My iPhone" or "iCloud Drive." However, attaching photos works fine.
When trying to attach files, the error "File exceeds allowed size" is shown even the file is tiny.
The same action works well in the PWA.
3CX onprem server, version 20.0.9.995
