Yealink Deskphone Provision

Firstly, ensure that the handset is currently in its default state. If the device is brand new, then this should already be the case, if not then you may need to go through resetting the device back to factory default first before proceeding. See Reset a Yealink for further information.

There are a few things you will need here as you go along.

The IP address of your device on your local network. (Your machine must be on the same network to gain access).
The MAC address of the device. (Can be found on a label at the back of the handset)
A Byphone user's Identity to provision the device with.

IP and MAC Address

Below are two possible ways to obtain the IP address.

Network Scan

If you already know the MAC address of the device, you could run a network scan on your local range. This will tell you all IP addresses in use on your network and the MAC address associated with them. If you can find the relevant MAC address within the scan, you will have been able to retrieve the IP address also and can use that in your browser to access the GUI of the device. A useful Windows tool for this is Advanced IP Scanner.

Via the PUI

Press the Menu Softkey (4th key) under the LCD screen.
Navigate to the Status section and press OK.
IPV4 will be the first entry showing your handset's IP address.
You should also see the MAC, and firmware versions etc. as well.

Accessing the Web User Interface

Once you have the IP Address of the handset you can access the WUI via your browser (while on the same local network). Navigate to the IP address in your address bar. If your base station is not in its default state, you will be met with a screen asking for a username and password: default username:admin and password:admin. If this is not the case please follow the instructions on the Reset a Yealink page.

You should now see a page similar to the image below.

Here you should see all of the information about your handset, including its Model/Phone Type, MAC Address and the IP Address you have just used to get here.

Now, go to the Settings tab, and select the Auto Provision section in the left Navbar.
On this page, you will need to set the Server URL for the Byphone system https://granite.byphone.co.uk/v1/provisioning/
Next, you must associate your handset with the Byphone system. Login to your Byphone phone system if not already.
Click on the Users option in the navbar on the left of the screen.
Select the User the handset will be associated with, then click on Add Device. (You will require an Identity for this User, if not already created please see Identities section on how to create a new Identity).
You should now be met with this device's settings page. Here you can alter the label that this device is known as within the system, please ensure that it is unique. You can see the Device Settings or delete the device if no longer required. We will concentrate on the device provisioning for now.
Enter in the MAC address of the device you are configuring, only alphanumeric characters, ignoring colons or dashes etc., and the external (WAN) IP address that the handset will be accessing from. (This ensures maximum security during provisioning. Incorrect details could result in a breach)
Search for an existing Identity in the Search Identities field and select the relevant one from the drop-down (You can add multiple Identities to a single base station, see Supported Hardware for restrictions).
Select the device model from the drop-down under Device Settings (Yealink T41S).
This will automatically populate the screen with the relevant number of function keys for that model.
You can edit the BLF keys as you see fit using the options as outlined below.
- None - This basically sets the key to do nothing at all when pressed.
- Line - This will allow you to add additional lines for incoming/outgoing calls, useful if you have added extra channels to this device.
- Park - This allows you to Park a call in a lot temporarily for retrieval later by either yourself or someone else, requires the Parking application, see the relevant section.
- Park Lot - Used in conjunction with the Park key, this allows you to configure keys to light up when a call is parked in that particular slot (9 possible), and when pressed pick up the call that is waiting in that slot.
- Group Voicemail - This key will light up when a message has been left in the Group Voicemail box you assign to it and allows retrieval of the voicemail using this key and the password for the mailbox.
- Day/Night Toggle - This key will light when the chosen Day/Night instance is in Night mode and will be unlit while in Day mode. You can toggle this using this key also.
- Speed Dial - This key will attempt to dial whatever number you associate with it. This can be an internal extension, an external number (landline, mobile etc.) or even an internal feature code.
- BLF - This key is to be associated with a user's extension number. This light will then flash when that user's devices are ringing (allowing them to be picked up if pressed when flashing), solid to indicate that the user is on a call, or off to indicate that the user is free, this can be pressed when off to dial the user also.
Clicking the Save & Activate Auto-Provisioning button on the Device Settings screen in the Byphone Portal allows 10 minutes in which this device can be auto-provisioned by the Byphone system. After 10 minutes, the provisioning server will be closed to this device (until the Save & Activate Auto-Provisioning button is pressed again).
Ensure that on your Yealink handset, you have the provisioning URL entered into the Server URL field, you will also see it again on screen. URL: https://granite.byphone.co.uk/v1/provisioning/ as noted in step 2. Click on the Confirm button to save those settings on the handset.
Now select the Upgrade section and click on the Reboot button.

The device will then reboot, forcing it to pull down your settings from the provisioning server. This should take a few minutes.

Once booting has finished, you can now make and receive calls using your new Yealink Deskphone.

** Minimum firmware required for T55A/T58A Teams handset is 58.15.0.85
