How do I set a Static IP address on a Cisco/Linksys phone?

Note: This guide is not compatible with the Cisco SPA525G phone.

The first step when assigning a Static IP address to anything is to gather the information specific for the network to which it will be connecting.

The information needed:

  • IP address the device will be assigned (ie. 192.168.X.X)
  • Subnet Mask (ie. 255.255.255.X)
  • Default Gateway/Routers IP address (ie. 192.168.X.X)
  • DNS Servers (Nextiva recommends using Google’s DNS: &

Once we have the IP address information it’s time to input it into the phone. To do this, you are going to want to press the Menu button  on the Cisco/Linksys phone. Scroll down to number 9 of the menu options. This option will be labeled as Network. Once the Network option is highlighted on the screen press the Select button.


Once Network is selected, the WAN Connection Type option of the phone will appear. By default the phone is set to DHCP. Press the edit button displayed on the screen of the phone.

After pressing the edit button, an option button should populate on the phone screen. Press the option button until you see Static IP on the phone screen.

When the phone displays Static IP for the WAN Connection Type press the ok button on the screen. Now the phone is ready to receive the information gathered at the beginning of this guide.

After pressing ok to set the WAN Connection Type a list of networking options will appear on the phone screen again. Using the directional pad  on the phone, scroll down until the Non-DHCP IP Address option is highlighted on the screen and press the edit button.

Once the edit option is selected the phone will allow you to enter the desired IP address gathered at the beginning of this guide. Note: Use the start button  for dots when entering IP addresses. Once the Non-DHCP IP Address is entered into the phone, press the ok button on the screen of your phone. (See Fig 2-6) Repeat these steps for the Subnet mask, Default Gateway, and DNS. Once all the information has been entered make sure you press the save button.  Then reboot the phone.
