How to Set a Static IP on my Cisco SPA525G2 Phone


To set a static IP on a Cisco SPA525G2, click the setup button (Paper icon), then select (8) Network Configuration. See a full list of steps here.
Note: We highly recommend consulting an IT or network professional when configuring advanced network settings. If able, the network administrator should always check the IP address, and assign and log any static IP to avoid conflicts in the future.

Switching a phone from DHCP to a static IP can be a useful way to address connectivity issues like URL call is disablederrors. It may also alleviate some (but not all) call quality issues.

Before You Begin

  1. Find out your phone's password. Cisco phones in an unprovisioned, factory default state and NOT running UC4.0+ firmware should be able to utilize 198y9w9y891 or 654123. Otherwise, use the MAC password.
  2. Next, determine the phone's current IP address and a static IP address (along with subnet and gateway) to assign to the phone.
