At Nooks, we’re making global calling compliant, smoother, and more reliable for go-to-market teams. If you’ve been told international calling is “easy” or “fully supported,” but then hit delays or dead ends, this guide will help you understand why – and how we’re doing things differently.
Expanding into international markets requires more than just a list of supported countries – it requires confidence that your calling platform can actually deliver. From provisioning local numbers to ensuring quality connections, there’s a lot going on behind the scenes. And not every dialer is up to the task.
What Actually Matters in International Calling
It’s easy to throw around big numbers when talking about international capabilities. But here’s what really matters:
- Registering your numbers
- Where you can call from
- Where you can call to
- How easily you can provision numbers
- Mitigating spam / telemarketing issues
Some platforms will show you a long list of countries – but that doesn’t mean they can easily provision numbers in those regions, calls will go through reliably, or remediate connect rate issues stemming from high spam reporting At Nooks, we’ve focused on delivering real, usable access – not just marketing claims.
Expanded Coverage: Call From More Countries
We’ve significantly expanded the list of countries you can dial from, giving global teams more flexibility to launch outbound motions wherever they operate. Nooks takes an API (or automated) approach to number provisioning – meaning less manual steps for teams who want international numbers.
Some dialing providers struggle with their international offering, because they prioritize their telephony costs over customer experience. This means a limited supported country list, only a handful of numbers actually accessible via API, and a whole lot of waiting time. These limitations often don’t show up until you’re deep in onboarding – or worse, mid-rollout.
Expanded Reach: Call To More Destinations
It’s not just about where your teams are based – it’s about where your buyers are. We’ve also expanded the countries Nooks can dial to, ensuring you can reach the people that matter most.
Some calling platforms appear to offer wide reach, but dig a little deeper and you’ll find inconsistencies: certain numbers don’t connect, others take weeks to provision, or they quietly limit support to only a few regions.
With Nooks, we’re transparent about what’s available and constantly expanding our reach, backed by a provider known for global reliability.
Easier Number Provisioning: Self-Serve, Streamlined, and Scalable
The process of getting numbers should be quick and seamless – not a black box. That’s why we focus on the way our customers source international numbers:
- We support provisioning via API in 45+ countries (and counting)
- Our process is built directly into the app, reducing back-and-forth and manual delays
- You’ll see what’s available, submit requests, and get numbers – without endless forms or follow-ups
This is in sharp contrast to platforms that require manual coordination, external teams, or private arrangements to access numbers. If it feels like provisioning is inconsistent or slow elsewhere, it probably is.
At Nooks, we believe you should be able to see what’s available, make a request, and move forward – fast.
AI-Powered Calling: Built for Performance Across Borders
International calling isn’t just about reach – it’s about performance after the call connects. If your AI can’t operate once the call goes through because of language restrictions, you’re not delivering on the core promise of a modern AI dialer.
Prioritizing AI, Nooks delivers:
- Voicemail Skip – Automatically detect and skip voicemails and dial trees to maximize rep efficiency.
- Real-Time Transcription & Summaries – Turn every conversation into searchable insights and actionable follow-ups.
- Parallel Dialing – Connect faster by dialing multiple leads simultaneously and prioritizing the first live response.
- Automated Scorecards – Automatically score calls to give managers visibility into rep performance at scale.
Why Your Subprocessor Matters (Even If No One Talks About It)
Here’s something most platforms don’t advertise: who powers their calling infrastructure. It’s a critical detail that affects everything from coverage to provisioning speed to call quality.
Nooks partners with Twilio, a globally respected communications provider with deep infrastructure and compliance across a wide range of countries.

For the second year in a row, Twilio was recognized by Gartner as a Leader in its 2024 Magic Quadrant for CPaaS. Gartner selected 11 different vendors in this market and analyzed each on its “Ability to Execute” (Y-axis) and “Completeness of Vision” (X-axis). Twilio was positioned the highest among others for our “Ability to Execute.” Gartner evaluates providers on the quality and efficacy of the processes, systems, methods, or procedures that enable IT provider performance to be competitive, efficient and effective, and to positively impact revenue, retention, and reputation within Gartner’s view of the market.
Other platforms may rely on alternative subprocessors or multiple providers stitched together behind the scenes. That can create coverage gaps, provisioning delays, or the need for manual workarounds to fulfill customer requests.
In some cases, providers might even list countries they can’t reliably support – hoping to figure it out later via private offerings or manual interventions. With Nooks, what we support is what we actually support.
Don’t Overlook Compliance
There’s one more critical element to international calling that rarely makes it into sales decks: compliance. Providers like Twilio, Vonage, and Telnyx have all made it clear – using international numbers without proper business registration is not just risky, it’s illegal. It’s the telecom equivalent of driving without registering your license plates.
At Nooks, we take this seriously. We work directly with Twilio to ensure our provisioning process aligns with local regulations and carrier requirements. That means when you source a number through Nooks, you’re doing it the right way – with the right documentation, the right process, and no shortcuts.
If another provider is skipping this step or claiming instant access to fully registered numbers across dozens of countries, it’s worth asking how. Because compliance isn’t just a box to check – it’s the foundation of reliable, long-term global calling.
Real Access, Not Empty Claims
International calling isn’t about who says they support the most countries – it’s about who can actually deliver.
With Nooks, you get:
- True global coverage (both from and to more countries)
- Reliable infrastructure powered by Twilio
- Streamlined number provisioning, built into the app
- Transparency about what’s available – no guesswork, no waiting games
If you’re expanding internationally, don’t settle for vague promises or hidden dependencies. Choose a platform that’s purpose-built for go-to-market teams – and ready to grow with you.
