Yealink SIP-T46U – Manual Network Configuration (Static IP Address)

When your phone is initially powered on it will automatically attempt to obtain valid DHCP settings from the local network.

If your phone is using a Wi-Fi connection make sure that Wi-Fi is enabled and connected properly before network settings can be obtained. See more information here.  

Static IP vs DHCP

If the automatic process fails or if your network does not use DHCP you will have to configure the phone's network settings manually using a static IP address. Manual network configuration can be performed from either the phone user interface or the web user interface.

Generally speaking, DHCP is more secure than a static IP address since the IP address is constantly changing. There are, however, certain situations where you would need to know the specific IP address of a phone (for example configuring constant network or firewall settings for the phone) making a static IP a more functional choice.

Contact your network or IT administrator to find out the required network values (IP address, subnet mask, default gateway address, and DNS address). The phone supports both the IPv4 and IPv6 address formats (IPv4 is enabled by default.) You can also switch a static IP configuration back to DHCP.

Phone User Interface

With the phone user interface, you can configure a Static IP address or switch a static IP back to DHCP. 

To configure a static IP address:

• From the idle screen navigate to Menu>Advanced>Network>WAN Port.
  
  If prompted for a password enter "admin" or the current administrator password.
  
  
• Depending on the addressing format of your network, press    or    or the Switch soft key to select or change the value in the IP Mode field to IPv4, IPv6, or IPv4 & IPv6.
  
  
  
  
• If you selected IP4 (or IPv4 & IPv6),  press      to select IPv4 and press the Enter soft key.
  
  
  
  
  press    or    or the Switch soft key to select Static IP from the Type field.
  
  Enter the desired values in the IP Address, Subnet Mask, Default Gateway, Pri.DNS and Sec.DNS fields respectively.
  
  To enter the period character (.) that separates values in each field, press asterisk (*) on the phone's keypad several times.
  
  
  
  
• If you selected IP6 (or IPv4 & IPv6),  press      to select IPv6 and press the Enter soft key.
  
  press    or    or the Switch soft key to select Static IP from the Type field.
  
  Enter the desired values in the IP Address, Subnet Mask, Default Gateway, Pri.DNS and Sec.DNS fields respectively.
  
  To enter the colon character (:) that separates values in each field, press asterisk (*) on the phone's keypad several times.
  
  
• If your company doesn't use a private DNS, Google’s public DNS server (address 8.8.8.8) is a popular choice for the primary DNS, but there are plenty of other options that might work faster for you. The secondary DNS is optional.
  
  
• Press the Save soft key to accept the change or the Back soft key to cancel.

To switch a static IP address to DHCP mode:

• From the idle screen navigate to Menu>Advanced>Network>WAN Port. 
  
  If prompted for a password enter "admin" or the current administrator password.
  
  
• Depending on the existing configuration press      to select either IPv4 or IPv6 and press the Enter soft key.
  
  
• press    or    or the Switch soft key to select DHCP from the Type field.
  
  
• Press the Save soft key to accept the changes or the Back soft key to cancel.

PPPoE Mode

If you are using an xDSL modem, you can connect your phone to the Internet via PPPoE mode. When activated the phone will perform a Point-to-Point Protocol negotiation to obtain the IP address. Contact your system administrator for the PPPoE user name and password.

To configure PPPoE via phone user interface:

• From the idle screen navigate to Menu>Advanced>Network>WAN Port. 
  
  If prompted for a password enter "admin" or the current administrator password.
  
  
• Depending on the existing configuration press      to select either IPv4 or IPv6 and press the Enter soft key.
  
  
• press    or    or the Switch soft key to select DHCP from the Type field.
  
  
• Enter the PPPoE user name and password in the corresponding fields.

Web User Interface

Configuration via the web user interface is only possible if your phone has previously been able to obtain an IP address automatically or by a provisioning process. It is useful for switching between DHCP and Static IP modes.

To configure the network via the web user interface:

• Access the web user interface as described here.
  
  
• Select the Network tab on the top and the Basic options from the side.
  
  
• Depending on the addressing format of your network, you can select or change the Mode (IPv4/IPv6) drop-down option to either IPv4, IPv6, or IPv4 & IPv6.
  
  
• If a static IP is already configured and you want to switch to DHCP, select DHCP under the IPv4 Config or IPv6 Config section..
  
  
• If DHCP is selected and you want to set up a static IP instead:
  
  
  • Depending on your selection in the Mode IPv4/IPv6 field, select Static IP Address under the IPv4 Config or IPv6 Config section.
    
    
  • Enter the desired value in the IP Address, Subnet Mask, Default Gateway, Primary DNS, and Secondary DNS fields respectively.
    
    If your company doesn't use a private DNS, Google’s public DNS server (address 8.8.8.8) is a popular choice for the primary DNS, but there are plenty of other options that might work faster for you. The secondary DNS is optional.
    
    
• You can also use a dynamic DNS by selecting OFF in the Static DNS field.
  
  A Dynamic DNS lets you use an easy to remember "static" domain name even when DHCP is enabled. It can be helpful if a static IP is not available to you but it does require you to register with a DDNS provider before you can use it.
