So, you want to implement communication functions in your app. Whether you’d like your users and customers to be able to make voice calls, video conference calls, or simply chat via the software, it’s now possible, all thanks to Communication Platform as a Service (CPaaS). Communication functions are integrated into the app via an API, helping businesses keep customer satisfaction high and hassle and complaints low.
Twilio Voice and Voximplant are two leading solutions in the CPaaS space. Are you considering integrating communication features into your API? Learn all about these tools and what they can do for your product.
What Is Twilio Voice?
Used by the likes of Lyft, Shopify, Airbnb, Netflix, Spotify, and many others, Twilio Voice’s API allows users to make, receive, and facilitate calls across the globe. Some of the solutions it offers are programmable cloud-based call centers, custom notifications, voice and video calls, burner phone numbers, tracking calls, and much more.
Twilio boasts that more than 9 million developers in more than 180 countries, and use the API to boost their apps.
Twilio Voice offers seamless integration.
Users praise Twilio Voice’s ability to integrate well with other software and products. The company offers plenty of tools and integrations for a seamless developer and user experience, both for the company and its consumers.
There is reliable support.
Another advantage of the API is that Twilio offers excellent customer service, solving queries readily and quickly, according to companies that have embraced it — even if you won’t need to use it often. The API is highly reliable and functional, and when there are (rare) glitches, Twilio acts on real-time feedback to resolve them.
You’ll need few external resources.
Developers can integrate Twilio Voice into their projects using their preferred language. They can also build their own tools to customize their products. You won’t need additional hardware or software.
Implementation requires technical skills.
The biggest complaint about Twilio is that it demands strong technical skills to implement into your project. In other words, if you’re not a developer, you probably won’t be able to use the API. Even for skilled developers with strong coding skills, the API can take a while to manipulate.
It’s pricier than some of the alternatives.
Twilio Voice is also relatively costly, especially when compared with some of the alternatives and competitors on the market.
Support may not be as good.
Because Twilio is a larger company, you have to jump through hoops in order to get what you need to be done. This is especially true when dealing with their client-side SDKs. Some of the errors can be very ambiguous.
Phone Number support can be sketchy
With some of our implementations, we have purchased numbers that were incorrectly advertised. For example, we bought a number for Austin, TX, only to learn that the number was actually for Rockport, TX, which is a nearby suburb. In addition, we have bought some numbers that show up on the block list from the git-go.
Another option is Voximplant. The platform enables real-time voice, video, and messaging features to be added to an app. Offering scalability, stability, and high functionality, it is a reliable API trusted by Hyundai, Home Credit Bank, KFC, Burger King, and many other businesses across a range of industries.
Voximplant is user-friendly.
A major check in the “pro” column is the fact that Voximplant is easy to use by people with a development background and those without one. You don’t need to implement complicated backend infrastructure, so really, people with less knowledge of coding can use the API alongside experienced developers.
Strong Developer Experience
VoxImplant has a very strong developer experience. The documentation is very strong and there are several platform-specific SDK’s. They even have a React Native SDK!
It’s highly flexible.
Another advantage of using Voximplant is that the API is flexible. It has a range of functionalities, and you can customize implementation, including scaling it as your app demands.
It offers strong documentation and developer tools.
Developers and users also praise the tool’s extensive, high-quality documentation, which includes plenty of examples and is kept up to date. Additionally, Voximplant offers around-the-clock support for any technical issues you may encounter.
It’s pricier than some alternatives.
The price point is the biggest customer complaint of Voximplant. The price is fairly steep compared to many of the API’s alternatives.
It is not as ubiquitous as some of its competitors.
Voximplant is not as widespread as Twilio Voice and other competitors, with fewer large companies and countries using the CPaaS. That means there aren’t as many phone numbers and features from other countries available to users should they need them.
Businesses in a wide range of sectors use CPaaS integrations in their apps, from video-streaming and online shopping to financial services and fintech to ride-sharing to real estate. Among other services, companies and organizations use them to facilitate:
So, which should you use — Twilio Voice or Voximplant? To get a better understanding, we drew up some of the key comparisons between the two:
Voximplant offers 60+ languages for TTS, compared to Twilio’s 26. Voximplant’s list of vendors includes Google, Amazon, Microsoft, Yandex, and Tinkoff. Twilio has only Amazon. If you have a Dialogflow bot, you can add it to calls using the Dialogflow connector to VoxImplant very easily.
Twilio requires communication between your application’s backend and Twilio’s servers in order to know how to handle calls and other operations. So it isn’t truly serverless per se. VoxImplant, on the other hand, does not require this. Control calls happen in real-time using JS deployed in the cloud. In addition, creating and debugging apps is a faster interaction with better reliability and lower total cost of ownership from within a web browser.
If you want to deploy a solution with Twilio Flex, you need to code. Alternatively, Voximplant Kit is a fully no-code solution for managers with no development resources.
Call latency outside the US.
Twilio data center network covers 8 regions, only 2 of them are located in Europe. Voximplants’ includes 14 countries, 9 in Europe, allowing for less latency outside the US.
Twilio relies on a single data center provider. Human errors or bugs can take Twilio offline. With Voximplant, if one out of the 14 data centers fails, users won’t notice it.
List of libraries.
Voximplant has a slight edge on “officially supported” libraries. They even support React Native. Twilio has a bunch of “community-supported” libraries, partially functional SDKs that aren’t supported by Twilio.
Both companies offer quality CPaaS features. But they will appeal to different businesses. In general, we would recommend VoxImplant over Twilio Voice for most implementations. They are a well-funded, up-and-coming company with the advantage of focus. They have a strong focus on call systems whereas Twilio covers a much wider range of offerings. We would only recommend Twilio if you plan to take advantage of integrations or synergies with some of Twilio’s other product offerings.
