Set Up Yealink desk phones to Use a Static IP Address

This article provides instructions on how to set up a static IP address for Yealink desk phones.

Switching a phone from DHCP to a static IP can be a useful way to address connectivity issues such as URL call is disabled errors.  It may also alleviate some (but not all) call quality issues.  You can set the static IP address through the phone menu, or through the web interface.

Ensure you have the following information before proceeding:

• Phone password

The phone password will be used to access the advanced settings within its menu. Yealink phones in an unprovisioned/factory default state should be able to utilize the password Admin.

• Current IP address and a static IP address (along with Subnet Mask and Default Gateway) to be assigned

Consult your 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.

Set up a static IP address through the web interface

Accessing the web interface of your phone makes it easier and more convenient to configure the settings.

IMPORTANT: To successfully access the GUI, make sure that the phone is connected to the network, and that the computer you will use is on the same network as the phone.

1. Enter the phone's IP address in the address bar of the browser.
2. Log in as an Administrator and enter the password.
3. Click on Network > select Static IP.
4. Enter the following:
   • IP Address
   • Subnet Mask
   • IP Gateway
5. For Static DNS, select On and enter your Internet Service Provider (ISP's) DNS or Google’s DNS server 8.8.8.8 as Primary DNS.
6. For Secondary DNS, enter your Internet Service Provider (ISP's) alternate DNS or the Level3 DNS server 4.2.2.2
7. Click Confirm to save your settings, then press OK on the prompt to reboot.

Wait for your phone to reboot. If it does not reboot, verify the information, then manually power cycle the phone (unplug it from the power source, wait a full minute, then plug it back in and let it power on).
