CPaaS delivers the reliability, security and global reach of legacy telecom without the performance blockers and security issues.

The internet is the most effective medium for scaling online communications to anywhere in the world, but it isn’t sufficient to provide a high-quality, secure experience. To maintain top-tier quality, some cloud communications providers are building bespoke infrastructure to pull calls into private routing environments.
This doesn’t mean you need to build your own global infrastructure to serve a global client base. Instead, you can choose a communications platform as a service (CPaaS) provider for real-time conversations that are embeddable, configurable and internet-centric.
Applications may rely on several different providers for their telephony needs including multiple providers for phone number provisioning, toll-free service, SMS and more. This adds unnecessary administrative burden as a unified provider can serve all these needs from a single pane of glass.
CPaaS vs. UCaaS
CPaaS and unified communications as a service (UCaaS) are similar in several ways, including their reliance on the cloud. However, UCaaS bundles products within a single platform while CPaaS enables à la carte customizations. CPaaS solutions also require additional tools and services like REST APIs and developer docs, while UCaaS solutions are generally ready to go out of the box.
Why CPaaS
CPaaS combines the most cutting-edge capabilities of the internet with the best practices of a successful platform business, providing programmable connectivity through APIs with the ability to embed communications into your applications.
CPaaS built on private, facilities-based infrastructure can enable more reliable, secure connectivity with a greater reach than the public internet can support. It also gives you far more control than the typical technology partner, especially with the self-service configurability of platforms like Telnyx.
The CPaaS market is unique for adapting the telecom model to the next generation of internet-centric voice applications. By building API-powered telecom services in the cloud and absorbing network operations into a software model, CPaaS bridges online technology into the future.
Choosing the right provider
The right CPaaS provider makes it easy to embed outbound calling and other great voice services into your apps, freeing up your engineering team to focus on growing your business in other ways.
The wrong CPaaS provider, on the other hand, can hamper your organization with retrograde technology and inflexible contracts. Choose a CPaaS provider with a culture of innovation that is committed to your growth.
Here are a few things to look out for:
The first obstacle to global voice is purchasing phone numbers in target markets — make sure you can get local, national and toll-free numbers. Look for a CPaaS provider with direct access to the primary market’s number supply, as well as embeddable and programmatic number searching.
Only facilities-based communications networks and cloud-agnostic telephony engines have the technical capacity to support real-time digital communications at scale. No amount of retrofitting internet or public switched telephone network (PSTN) will result in the clear and global communications modern users demand.
International service requires more than a number to connect an outbound call. Check that your international carrier supports backward compatibility with the local PSTN and compliance with local regulators.
You don’t need to build your own infrastructure to execute your global vision. CPaaS delivers the reliability, security and global reach of legacy telecom without the performance blockers and security issues.

What is Telnyx CPaaS? Telnyx CPaaS is a programmable communications platform that lets businesses add voice, messaging, and phone numbers to their applications using APIs. It combines carrier-grade connectivity, real-time control, and global reach for enterprise-scale workloads.
What features and services are included in Telnyx CPaaS? Core services include programmable voice with call control, SMS and MMS, real-time media streaming, and global phone numbers. Enterprises also get security and compliance features, analytics, and 24/7 customer support.
How does Telnyx compare to Twilio as a CPaaS? Both offer APIs for voice and messaging, but Telnyx operates a private network while Twilio relies more on third-party carriers. That infrastructure choice can affect latency, voice quality, control, and total cost.
Does Telnyx support MMS and how is it different from SMS? Yes, Telnyx supports MMS for images, video, and other media alongside SMS for text-only messages. The practical differences in payload size, formatting, and pricing are detailed in this SMS vs. MMS breakdown.
Can I send group or broadcast MMS with Telnyx CPaaS? You can implement either group threads or one-to-many broadcasts based on how you want recipients to receive and reply. The tradeoffs between reply-all conversations and individual outreach are mapped out in this MMS group or broadcast overview.
How do developers get started building with Telnyx CPaaS? Most teams start by creating a project, provisioning numbers, and testing messaging or voice APIs in a staging environment. The fastest path is to use the Telnyx Developer Center for SDKs, quickstarts, and tooling.
Does Telnyx offer global phone numbers and international coverage? Yes, you can acquire and manage local, toll-free, and national numbers across many countries from a single account. Coverage varies by market, but the platform supports number provisioning, porting, and regional compliance controls.
