Package Contents

The following items are included in your package. If you find anything missing, contact your system administrator.

We recommend that you use the accessories provided or approved by Yealink. The unapproved third-party accessories may result in reduced performance.

Assembling the Phone

1. Attach the stand:
   
   You can also mount the phone to a wall.

2. Connect the handset and optional headset:
   

3. Connect the network and power:
   You have two options for network and power connections. Your system administrator will advise you which one to use.
   

The IP phone should be used with Yealink original power adapter (5V/600mA) only. The use of the third-party power adapter may cause the damage to the phone. If you are connecting a PC to your phone, we recommend that you use the Ethernet cable provided by Yealink

If inline power (PoE) is provided, you don’t need to connect the power adapter. Make sure the hub/switch is PoEcompliant. PoE is only applicable to the SIP-T31P/T31G IP phone.

Startup

After the IP phone is connected to the network and supplied with power, it automatically begins the initialization process. After startup, the phone is ready for use. You can configure the phone via phone user interface or web user interface.

Network Settings: Click on Network- >Basic->IPv4 Config

You can configure the network settings in the following ways:

DHCP: By default, the phone attempts to contact a DHCP server in your network to obtain its valid network settings, e.g., IP address, subnet mask, gateway address and DNS address.

Static IP Address: If your phone cannot contact a DHCP server for any reason, you need to configure the IP address, subnet mask, gateway address, primary DNS address and secondary DNS address for the phone manually.

The IP phone also supports IPv6, but IPv6 is disabled by default.
Wrong network settings may result in the inaccessibility of your phone and may have an impact on the network performance. Contact your system administrator for more information.
