The Telnyx network offers unparalleled security, reliability and call quality. That’s because we’re a true carrier, and unlike many CPaaS providers, we don’t rely on middlemen to provide core communications functionality and routing.

We built our SIP services so that you can easily integrate Telnyx with any platform to get your business communications set up quickly. Whether you’re looking to integrate with hardware or cloud-based solutions we want to empower you to make and receive calls globally with the network built for reliable, enterprise-grade voice services.

This guide shows you how to connect your Telnyx numbers to Yealink T Series IP phones. Yealink T Series IP phones are IP based hard phones which are SIP compatible. Yealink provides video and voice communication technology solutions that meet the business needs of any organization. Configure this PBX for making and receiving calls over the internet through a next-generation carrier like Telnyx!

What you’ll need to get started:

  1. A Telnyx account
    • Sign up here with your email address, or register with your Google, Facebook or GitHub account - it only takes a few seconds.
  2. A Yealink T Series IP phone.

How it works

A Telnyx Elastic SIP Trunk is used to connect your IP-based communications infrastructure to the PSTN, so you can make and receive calls globally with our private IP network. We handle all the complexity in routing calls and delivering crystal clear conversations. To connect your Telnyx numbers to your Yealink T Series IP phones we need to establish a SIP interface which is completed in these steps:

  1. Set up your Telnyx SIP Trunk Connection.
  2. Authenticate your SIP Trunk with your Yealink T Series IP phones.
  3. Configure your Yealink T Series IP Phones profile for Inbound and Outbound calling.

Getting Started with Your Telnyx Mission Control Portal

There are four steps needed to set up your Telnyx Mission Control Portal account so that it’s ready to be configured to your PBX phone system, softphone client or softswitch of your choice.

Level 1 Verification:

To complete the below steps, you'll need to be Level 1 verified. Most users will already be Level 1 verified following email confirmation on signup. To check, visit the ‘My Account’ section of your portal account, and navigate to ‘Verifications’. More information on account verification can be found here.

Connection Setup

Next, you need to set up a connection to authenticate your client (Yealink T Series IP phone) with our sip proxy (sip.telnyx.com).

These steps will walk through the setup of a credentials based connection.

  1. Go to ‘Connections’ from the side navigation
  2. Click the "+ Add Connection" button near the top right corner of the page.
  3. Enter the name you wish to have for your connection.
  4. Select "Credentials" as the "Connection Type".
  5. A username and password will automatically be generated but you change the credentials by clicking the "edit" button to the left. Please make sure you use strong credentials.
  6. Click "Set Credentials".
  7. Click "Done"

Note: Once your Credential connection is created, you can display the username and password by clicking the eye icon under the "Auth Detail" column.

DIDs

A DID is required in order to receive inbound calls to your client. After you purchase a DID on your account, you'll have to assign the connection you wish to receive inbound calls to. Information on assigning DIDs to a connection and DID features can be found here. More details on our number search feature can be found here.

Outbound Profile

An outbound profile is required in order to make outbound calls. More information on creating an outbound profile and its features are explained here.

Setting up SIP Trunk configurations on the Yealink T Series IP Phones platform is pretty simple. To connect a SIP Trunk, we need to specify inbound and outbound signaling for Telnyx, set up authentication, add our numbers and set up some headers.

Before you connect your Yealink IP phone to the Telnyx network, setup your phone and connect it to an Ethernet port with internet access.

There are two ways to setup your VoIP account and connect your IP phone to the Telnyx network:

  • Using the phone’s keypad.
  • Using the phone’s web interface.

Setup Using the Keypad

  1. Press the “Menu” button.
  2. Navigate to “Advanced”.
  3. Enter the default password. This should be "admin" unless you manually changed it.
  4. Navigate to “Accounts”.
  5. Select an empty line and fill in the following fields:
    • Activation: Set to “Enabled”.
    • Label: Enter the name you would like displayed on the screen of your Yealink phone (i.e. “John Doe”).
    • Register Name: Enter the username from your credentials based connection in the Telnyx Mission Control Portal.
    • User name: Enter the username from your credentials based connection in the Telnyx Mission Control Portal.
    • Password: Enter the password from your credentials based connection in the Telnyx Mission Control Portal.

Your VoIP account is setup and connected to your Telnyx SIP trunk.

Setup Using the Web Interface

  1. Before you can setup your phone using the web interface, you need to get the phone’s IP address. Follow these steps to get the phone’s IP address:
  2. Press the “Menu” button on the phone.
  3. Navigate to “Status”.
  4. The phone’s IP address will be displayed as “IPv4” on the screen.
  5. Once you have the IP address, enter the phone’s IP address in the URL bar of your web browser.
  6. Login using these default credentials:
    • Username: admin
    • Password: admin
  7. Click the “Account” tab.
  8. Enter the following information for Account 1:
