DISCOVERY
Users could manually discover the device by specifying the IP address or scanning the entire LAN
network. Three methods are supported to scan the devices.
• PING
• ARP
• SIP Message (NOTIFY)
Click on "Auto Discover" under web UI-> PBX-> Zero Config->Zero Config, fill in the "Scan Method" and
"Scan IP". The IP address segment will be automatically filled in based on the network mask detected on
the UCM6100. If users need scan the entire network segment, enter 255 (for example, 192.168.40.255)
instead of a specific IP address. Then click on "Save" to start discovering the devices within the same
network. To successfully discover the devices, "Zero Config" needs to be enabled on the UCM6100 web
GUI->PBX->Zero Config->Auto Provisioning Settings.
