hope someone can help me with this.
I've tried deploying the 3cx Debian ISO on a Hyper-V host that is running on Windows 10.
After Installation I only get weird hieroglyphic text output from the VM.
I gues I opened the thread a bit prematurely, sorry for that.
Turns out I had the same problems with a regular debian installation on that VM. After deleting the VM and provisioning a new one things work as they should.
