(T41/T42/T46/T48)

Make sure before you start that you have an extension available on your account (https://wiree.io/portal). To create an extension in your Wiree account, click on PBX Extensions, and then “Add Extension” (If you are using a SIP Trunking or Residential Account, click on SIP Trunks, and then “Add Extension”). When configuring the Yealink phone, you’ll want to use the “Register Username” (not the shortened Extension Number) and the Password of the Extension you’ve created:

Take note of the following fields, highlighted in the image below, as you’ll need these to setup the device. 

  • Register Username: This is the full username, not the short Ext No.
  • SIP Proxy: The server you’ll be connecting to.
  • Re-Register Interval: Defines how often your device should check in.
  • Password: The extension’s password

Note that if the extension is already configured on a device, you’ll need to reconfigure, power down or factory reset the currently connected device before the required information will be displayed.

NB: If your phone has been used with another provider in the past, please factory reset it before continuing. To do so, hold OK for about 8 seconds, until you see the ‘Reset to Factory?’ prompt, then press OK.

To configure the Yealink T4 Series to your Wiree account, first retrieve the IP Address so that you can log into the ‘Web Configuration’ via your computer. To do this, the press the ‘OK’ button in the middle of the D-Pad. The IP Address should show up in the Status Page. Enter The IP Address into your web browser.

Once you are on the Web Configuration page enter the username and password. By default the username will be ‘admin’ and the Password will be ‘admin’.

Once you have successfully logged in, click on the ‘Account’ tab across the top. Fill in the highlighted fields below, copying the Register Username, Extension Password and SIP Proxy from the configure PBX Extension dialogue:

YealinkMy Account Portal
Register NameRegister Username
User NameRegister Username
PasswordPassword
Server HostSIP Proxy

Hit the ‘Confirm’ button at the bottom of the page to save the details. Once the page has reloaded, click on advanced and type ‘50002’ into the ‘Voicemail’ field, and change the “Caller ID Source” from “FROM” to “RPID-FROM”. Again, hit ‘Confirm’ to save the settings.

Next, click on the ‘DSSKey’ tab at the top. In here you will configure multiple DSS keys to all use Account 1 on the handset, allowing you to make, receive and manage multiple calls through your extension number, by showing each call on its own DSS Line key.

Feel free to also set up some Speed Dials for important numbers. If you would like to set up BLF (Busy Lamp Field) to see the status of the other extensions please refer to the BLF Guide: Yealink BLF Configuration

Now that the lines have been configured, set the time zone and time format, which can be done under the top ‘Settings’ tab, and then the ‘Time and Date’ button on the left.

At this point, the phone should be ready to go. If you have any troubles making and receiving calls from here on in, please give Wiree a call on 02 8880 9900.

Additional Settings

NBN Users

If you experience audio issues when there is more than one concurrent call in progress on your NBN connection, you may need to change the NBN traffic class used by your voice traffic. There are two options for traffic classes below – if you’re experiencing issues with one, please try the other.

To access this setting, choose Network > Advanced and locate the QoS section.

TC1 – High Priority, but limited bandwidth.

This traffic class can only support a limited number of calls (normally 1), depending on how much bandwidth has been purchased by your ISP. This is different to your normal (25/5, 50/20, etc.) bandwidth.

Audio QoS: 46

SIP QoS: 26

TC4 – Lower Priority, with all available bandwidth.

Phones in this traffic class will be able to utilise the full bandwidth of your NBN connection (eg. 50/20)

Audio QoS: 26

SIP QoS: 26

SIP Port Number

On some routers, it may be necessary to manually set each phone to a different local port number to mitigate some NAT related problems. To access this setting, choose Settings > SIP and locate Local SIP Port

For each device you’re changing, we recommend incrementing this port number, beginning at 5070 for the first handset, 5071 for the second, etc.
