Architecture	Scope	Type	Silent switches	Source
x64	machine	MSI		Default for MSI

Declared by publisher means the switches come straight from the winget manifest the publisher (or community maintainer) submitted to microsoft/winget-pkgs.
Default for {type} means the manifest doesn't specify silent switches, so the framework's standard switches are shown (e.g. /S for NSIS, /quiet /norestart for MSI).

Frequently asked questions

What is the silent install command for 3CX?

3CX uses MSI. After downloading the installer, run: msiexec.exe /i 3CXTAPI18.msi /quiet /norestart. The silent install switches are /quiet /norestart.

How do I deploy 3CX via Intune or Configuration Manager?

Use winget for the cleanest path: winget install --id 3CX.MultilineTAPI --exact 1.0.126 --silent --accept-package-agreements --accept-source-agreements. If winget isn't viable in your environment, package the publisher's installer directly using the silent switches above.
