Unable to access the WebUI
Log–in page from computer.
The computer is not
connected to the same
subnet (network) as the
Deskset, and the subnets are
not set up to communicate.
 Verify the IP address. You must correctly enter the IP
address of your Deskset into your Internet browser’s
address bar. At the Deskset, press MENU –> 4 to see the
IP address displayed in the third line of the information.
 Ensure that there is an Ethernet cable attached to
Network port on the Deskset and to the LAN. If a PC at
the same workstation is sharing the LAN connection,
attach an Ethernet cable to your computer’s Ethernet port
and to the PC port on the back of the Deskset.
 Confirm that your computer and your Deskset are on the
same subnet so that they can talk to each other. Check
that the first three sections of each IP address are the
same. If they are not, they may not be connected to the
same subnet. Contact the installer; the subnets may not
be set up to communicate.
The local address, rather
than the network IP address,
was used in the address line
of the browser.
 Use the network IP address assigned through DHCP or
manually in the address bar of the browser.
