Setting Up Your Phone

What you'll need

Before you begin installing your service, please make sure you have the following equipment:
A Cisco 8841/8851 and 8861 phone body.
•
•
A handset and cord.
A desk stand.
•
•
A CAT 5 Ethernet computer cable, to connect the phone to your router.
A power supply unit, including a plug lead and clip, assuming you're not using Power Over
•
Ethernet switches or ports.
A sheet with your phone number, online account user details and voicemail PIN - this is
•
important information, so please keep it somewhere safe, even after set-up.
•
A working Ethernet LAN with Ethernet broadband router - USB routers and modems are not
compatible.
A Power over Ethernet switch - or Ethernet switch - depending on your installation.
•

Assembling the phone

Now, start by putting the phone together in the following order:
•
First, find the coiled handset cord. Plug it into the smaller socket on the underside of the
phone - this is marked with a phone symbol.
Now, take the other end of the handset cord and plug it into the handset.
•
•
Line up the phone stand and the tabs with the slots on the underside of the phone. Slide the
bottom tabs into the slots and press lightly down on the top of the desk stand - don't force it.
Next, push the power brick into the plug unit and plug the power lead into the phone, to
•
assemble the power supply unit.
•
Connect the computer cable to the underside of the phone in the socket monitor/pc icon.

Connecting to your router

Before connecting the service, make sure your router is set up to perform NAT (Network Address
Translation) and act as a DHCP server - normally a default setting on most routers (a fixed IP
address is not supported).
Next, plug the Ethernet cable from the phone into your router. Once powered up, an IP address
should automatically be allocated to the phone through DHCP. It's also important to make sure the
following ports are not blocked by the firewall within your router or at any point through your access
provider.
