    I try to use the button to scan devices on my subnet, it work but only in the same subnet of my server

    ex:

    -I scan 10.16.48.40/24 it work

    -I scan 10.244.4.0/22 it’s doesn’t work

    Is there something I need to enable to permit VPBX to scan or there something on my network who can block that action?

    Is not detecting any device, you should check the network infrastructure in your company.

    Like I said they are not on the same vlan, So Nmap won’t show any MAC.

    If i understand the scan subnet for devise button use the command nmap, so I will never be able to use the button.

    Yes, it use nmap command to discover the devices in the network
