Telnyx vs. Twilio for Programmable Voice

Compare Telnyx vs. Twilio for programmable voice across network, telephony features, API, price, support and user reviews.
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
TelnyxTwilio
Network TypePrivate 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 OwnershipFully 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.
CloudMulti-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.
Guaranteed Uptime SLA 99.999%
We guarantee five-nines of uptime thanks to our superior network and unmatched support.
99.95%
That's the equivalent of more than 21 minutes of downtime every single month.

In order to deliver a 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.
