XML markup languages for programmable voice
Before diving into the migration process, it’s important to understand the purpose of XML-based languages like TeXML and TwiML.
An XML-based markup language is a type of computer language that uses a set of rules for encoding documents in a human- and machine-readable format. The design goals of XML (eXtensible Markup Language) emphasize simplicity, generality, and usability across the internet.
Ultimately, XML languages provide a flexible and efficient way to define, store, and transport structured data, making them a cornerstone of modern data exchange and web technologies.
Understanding the basics: TwiML vs. TeXML
When considering which XML-based language to use, you’re often choosing between which solutions offer language systems that work best with their software and platforms.
Twilio’s markup language, TwiML, is an XML-based language designed to handle communication tasks such as voice calls and SMS messages. It's known for its simplicity and ease of use, making it a popular choice among developers.
Telnyx’s TeXML offers the same capabilities and ease of use but with access to Telnyx’s private global network and Voice API. Developers looking to create sophisticated communication solutions with Telnyx’s suite of tools can use TeXML to build those systems.
Take a look at our comparison guide for a more in-depth look at the differences between TwiML and TeXML.
Key considerations when switching from Twilio to Telnyx
If TwiML and TeXML have the same capabilities, you’re likely wondering if moving your programmable voice solutions to Telnyx is the best idea. After all, you’ve already invested a lot of work in building your solutions in Twilio.
Below is a high-level overview of the differences between Telnyx’s and Twilio’s offerings. Check out our comprehensive guide to see a full comparison and understand which solution is best for your use case.
We designed our private global IP network for real-time voice and data communications, so your calls are crystal-clear, secure, and have super-low latency.
Twilio uses the public internet, which wasn't built for real-time communications. High latency, packet loss, and poor security cause endless quality issues.
Telnyx offers pay-as-you-go pricing with automatic volume-based discounts as you scale. Telnyx voice starts at $0.005 per minute (nearly 50% less than Twilio).
Twilio programmable voice costs 50% more than you'd pay with Telnyx.
|24/7 free support
Telnyx offers round-the-clock support to all customers—regardless of size or spend—at no additional charge.
Twilio's premium support plans come at an additional cost, and their free support only covers basic needs.
The 7-step migration process from TwiML to TeXML
Moving your programmable voice solutions from Twilio to Telnyx might seem daunting at first. But with our streamlined seven-step migration process, you can make your move quickly and easily. Whether you're looking to harness advanced call control, dive into complex routing capabilities, or simply want a more flexible telephony solution, these steps are your blueprint to success.
Let's break down this transformation into seven simple stages, paving the way for a smoother, more powerful communication experience with Telnyx.
Check out our developer documentation for a more technical, in-depth explanation of the migration process.
1. Initiate a TeXML application.
Start by setting up a new TeXML application within the Telnyx portal. This process involves naming your application and configuring it to interact with your existing backend server.
2. Transfer your TwiML Bins instructions to TeXML Bins.
If you're currently using TwiML bins, TeXML offers a similar feature. You'll need to transfer your instructions to the TeXML Bin and ensure they align with your new application's settings.
3. Link a number to your application.
Assign a telephone number to your TeXML application. This number will be the point of contact for your test calls.
4. Conduct a test call.
Make a test call to the assigned number to ensure everything you’ve set up everything correctly. This step is crucial to verify the successful integration of your TeXML application.
5. Configure your endpoints.
Adjust the endpoint address to Telnyx's TeXML endpoint. This change is essential for your application to communicate correctly with the Telnyx system.
6. Authenticate your setup
Update the authentication header as per Telnyx's guidelines. If you don't have an API key, you'll need to create one in the Telnyx portal.
7. Execute requests
With the endpoints and authentication set, you can start making requests to control your TeXML application.
By following these steps, you'll have successfully migrated your application from TwiML to TeXML, tapping into Telnyx’s robust network and platform.
Best practices for a smooth transition
Following the steps above should be relatively seamless. But if you want to make your migration from Twilio to Telnyx even easier, we suggest following the best practices below:
Migrate your solutions incrementally
While we would love for you to go all in on Telnyx immediately, you should consider migrating in phases, especially for large systems.
By dividing your migration from TwiML to TeXML into smaller segments, you can identify and resolve any issues early on, ensuring minimal disruption to your operations. An incremental migration also simplifies the troubleshooting process, as you can more easily pinpoint and address problems when you make changes in a controlled, phased manner.
Furthermore, this approach allows for feedback integration after each stage, facilitating continuous improvement. The knowledge gained in the early phases can be applied to later ones, enhancing the efficiency and effectiveness of your migration. Additionally, incremental migration helps in effective resource management and reduces the strain on personnel and infrastructure. Each successful stage of the migration builds confidence among the team and stakeholders, securing ongoing support for the project.
Ultimately, an incremental migration strategy ensures a more controlled, adaptable, and successful transition from TwiML to TeXML.
Leverage our extensive support and documentation
Engaging with Telnyx’s support docs grants you access to expert knowledge and practical insights. Perusing support articles and developer documentation before your migration can help you anticipate roadblocks or challenges before they cause problems.
Make the switch from TwiML to TeXML
Migrating from TwiML to TeXML can significantly enhance your telephony applications' capabilities and reduce your communications costs. By understanding the differences between the two solutions, you can carefully plan your migration to take advantage of Telnyx’s private global network, free 24/7 support, and lower price tags.
