Telnyx vs. Twilio for Programmable Voice

Businesses today are increasingly leveraging programmable voice APIs to embed sophisticated communications capabilities into their applications, enabling them to better meet the needs of today’s end users. In fact, around 85% of the world’s top performing organizations believe that APIs are crucial to the growth of their company.

And why not? Unlike rigid solutions of the past, voice APIs are highly configurable and easily consumable—enabling forward thinking businesses to progressively build upon them to meet customer needs, while at the same time lowering operational costs.

But, choosing the right programmable voice provider can have a big impact on your user experience, as well as your ability to scale efficiently. Let’s take a look at the key differences when using Telnyx and Twilio for programmable voice, to demonstrate the monumental impact these differences can have on your overall experience.

Telnyx vs. Twilio for network

Let’s face it—your calling experience is largely determined by your underlying voice provider. And, most providers traverse your traffic over the public internet, where it’s susceptible to packet loss, lag and jitter. Telnyx and Twilio have taken vastly different approaches to building their communications networks. Let’s break that down:

Telnyx vs. Twilio: Communications Network

	Telnyx	Twilio
Network Type	Private network Our global IP network was designed from the ground up for real-time voice and data communications, so your calls are crystal-clear, secure, with super low latency.	Public internet The internet was not built for real-time communications, and it shows - with high latency, packet loss, and poor security consistently causing call quality issues.
Network Ownership	Fully owned We control our infrastructure, so we control routing, quality, and traffic for high-quality calls and low post-dial delay.	Network reseller Using other providers’ servers and middlemen for routing and telephony leads to persistent routing and quality issues.
Cloud	Multi-cloud Our network points of presence leverage AWS, Google Cloud and Azure for added redundancy.	Single-cloud Relying solely on one cloud provider for all network services increases the risk of network failure.

Telnyx vs. Twilio for telephony

In order to deliver a truly great programmable voice experience, your provider needs to cover the basics well. Traditional telco features like number inventory, porting and carrier licenses make a huge difference when it comes to scaling your communications.

The right provider will have the resources and processes to support easy scaling, to free up your teams and get things done faster.

Telnyx vs. Twilio: Telephony

	Telnyx	Twilio
Number Inventory	Deep number inventory Licensed carrier status in 30+ countries worldwide and close partnerships with Tier-1 carriers in over 140 countries for numbering.	Indirect number inventory Middlemen and resellers add markups and restrictions to Twilio's numbering inventory, meaning you pay more for a worse selection.
Number Porting	FastPort® Streamlined, automated, self-service porting process with real-time data validation and on-demand activation.	Manual porting Document-heavy, opaque porting process that can take up to four weeks.
Carrier Status	Licensed carrier Status in 30+ countries, ensuring full regulatory compliance and access to local telephony assets.	Not a licensed carrier No guarantee of regulatory compliance and restrictions on number access and telephony operations.

Telnyx vs. Twilio for Programmable Voice API

Now that we’ve explored the differences between Telnyx and Twilio when it comes to network infrastructure and telephony features, what about their programmable voice APIs? These features impact developer experience, and also that of the end user.

Telnyx vs. Twilio: Programmable Voice API

	Telnyx	Twilio
Latency	less than 1s response time Using an edge-stack approach, we route your data via the closest server to your application—delivering market-leading low latency.	3s+ response time Twilio has a greater reliance on the public internet. The result is noticeably higher latency levels and a less consistent experience.
Real Time Commands	Real time communications The Telnyx Call Control API can receive real-time commands throughout the call for interactive command and control.	Scripted communications TwiML requires pre-scripted workflows at the start of the call, meaning real-time decision making and control just aren’t possible.
XML Scripting	TeXML is Telnyx's XML-based markup language that is at full feature parity with Twilio's TwiML. That means you can use your existing TwiML code and it will work seamlessly with TeXML, cutting development time to migrate significantly.	TwiML is Twilio's XML-based markup language used to instruct how to handle voice calls and SMS and MMS messages.
