The idea of getting started with a calling solution or integrating voice into your applications can be daunting. But with the Telnyx Mission Control Portal—awarded “Most Implementable CPaaS Platform” by G2—getting started with voice is easy.

To show you just how easy it is, our VP of Business Development, Mclain Roth, will walk you through the process of:

  • Buying a number
  • Setting up an outbound voice profile
  • Creating a TeXML application with TeXML Bin instructions
  • Testing the app in just five minutes.

Your 7-step guide to getting started with Telnyx Voice API

Here’s your quick and easy guide to set up and start using Telnyx Voice API. In just seven steps, you can create your first voice app.

1. Log in or create a Mission Control Portal account

Navigate to the Telnyx Mission Control Portal, your gateway to managing all your Telnyx services. Log in or create an account to get started.

2. Acquire a phone number

Before you can use Telnyx’s voice offerings, you have to buy a number. Telnyx offers local calling in 49 countries and PSTN replacement in more than 45, with more coming soon.

To buy a number:

  1. Go to the "My Numbers" page or use the "Search and Buy Numbers" feature to find a phone number. You can search by various criteria such as area codes and number features.
  2. Add numbers to your cart and check out, just like you would with any other online shopping experience.

3. Assign the number

Once you have your number, you can assign it to a service. To do this, you could set up a SIP trunk or connection. However, for a more streamlined approach, Telnyx offers a programmable voice option through creating a "bin."

TeXML bin hosts an XML file for you, eliminating the need for your own server infrastructure.

4. Create a voicemail system

In the demo video, Mclain follows our Developer Docs tutorial on getting started with TeXML Bin. Using TeXML Bin, you can use pre-written code from Telnyx's Dev Docs guide or your own code with a pre-recorded message.

This bin will serve as the backend for your voicemail system.

5. Set up an application

Now you’re ready to create a TexML application within Telnyx. This application will instruct Telnyx to refer to your Bin instructions when a call comes in. You'll need to copy the bin's URL into the application settings and ensure the application is configured for outbound calls.

6. Configure outbound calls

Creating an outbound voice profile is crucial for controlling where calls can be directed. You can select specific countries or regions you wish to call. Assigning the TexML app to this profile ensures that outbound calls adhere to your predefined settings.

7. Finalize and test

After saving your settings, your number is ready to use. Testing the system is as simple as making a call to the number you set up. The call will be routed through your TexML application, playing the pre-recorded voicemail message. If you've enabled recording, you can review the message in the call recordings section of the portal.

You’ve just created your first voice app using Telnyx

Getting started with Telnyx Voice is just a few clicks away. As you’ve seen, Telnyx Mission Control Portal offers a seamless way to set up a voicemail system without the need for complex voice coding or SIP trunk setup.

By following Mclain's demo, you can quickly establish a voicemail system, ensuring you never miss important calls. Whether for business or personal use, this solution is designed to meet your telecommunication needs with ease and flexibility.
