Important

  • Router Phones: T42U, T43U, T46U, T48U
    Router Phone - A Router Phone or an SBC is required to bundle all SIP traffic over a single TCP port and direct the signalling to the IP Phones. At least one Router Phone is required if your 3CX System is in the cloud or its remote phone connected to an on premise system.
  • If it’s an old phone, you might have to upgrade its firmware to the latest 3CX supported version. See how to do this here.
  • Yealink T41P, T42G, T46G and T48G are end of life. Follow this guide.
  • If you don't want to use RPS, you have to enter the provisioning URL into the phone via its web interface. The phone will be configured automatically and then restart. Use the DHCP option 66 if you have a large number of identical legacy phones (as the URL is different for each phone).

Yealink T4 phone model and MAC address

Be sure you follow the steps for the right phone model. You can find the model and MAC address on the label at the back of the handset, or by pressing the “Menu or OK > Status” on the phone.

Take a note of the MAC address, you will need this for the configuration. Find out more about your IP Phone MAC address.

Step 2: Add The Phone to the Extension

From the admin console in your web client:

  1. Go to Users and select the user you want to add a phone for.
  2. Click on the IP Phone tab. Click Configure a phone to add a phone.
  3. Now select your phone model from the dropdown menu.
  4. Enter the phone’s MAC address without dashes or colons, and click Add phone.

Step 3: Router Phone, SBC or LAN?

Configuring IP Phone

  1. If 3CX is on the cloud, you must use a router phone or SBC:
  1. If it is not a router phone you need to specify one or an SBC.
  2. If the phone is a router phone you can configure it to connect directly if you prefer.
  1. If 3CX is on premise or self hosted, you have an additional option, you can select “Local LAN/VPN”.
  2. Click Add Phone to save the phone configuration for this extension.

Step 4: Connect the Phone

3CX will now create provisioning information for the phone and make these available on the provisioning URL. The phone must connect to this URL to retrieve its configuration information and authentication details. You have the following options:

  1. RPS - Connect the phone to the network within 14 days. If it is already connected, restart it. The phone will be configured automatically and restarted.
  2. PNP - If 3CX is on premise or connected via SBC, you can connect the phone to the LAN and look for it in the PNP dialog (Admin Console > Phones > PNP Phones). Right click and assign it to the extension you configured above.

Assigning a phone to an existing user

  1. Alternatively you can login to the phone's webUI and enter the URL manually. You can also use DHCP option 66.
