Telnyx owns its carrier network, so voice and messaging run at roughly half Twilio's list rates with lower latency. We integrate Telnyx into your product, and when you are on Twilio paying too much, we migrate you (TeXML keeps your call flows, FastPort moves your numbers) with no downtime. First plan in 2–3 weeks, from $3K. 20 years of telephony behind it.
Whether you are integrating Telnyx for the first time, scaling voice and messaging already on it, or watching a Twilio bill climb past what the feature is worth, we have shipped telephony both ways: building on Telnyx and migrating teams onto it.
Twilio is easy to start and bills every minute and message at list rates. Telnyx runs the same channels on a network it owns, for roughly half, but the migration and the edge cases are real. A specialist has shipped Telnyx in production and ports you without downtime.
On Twilio and the bill is climbing? We model the Telnyx saving and migrate you with TeXML and FastPort. Starting fresh? We integrate Telnyx right, with compliance and deliverability from day one. Want the Twilio comparison? See Twilio development.
A telephony build is more than an API key: it is channels, compliance, deliverability, and a cost model. Here is the architecture we build, whether you integrate Telnyx fresh or migrate from Twilio.
Which Telnyx products and channels, expected volumes and regions, and the projected bill. For migrations, we model your Twilio spend against Telnyx and map the TeXML and porting work.
Wire Telnyx Voice, Messaging, SIP, and Verify into your app, or map existing Twilio TwiML to TeXML so your call flows run on Telnyx with minimal rewrite.
IVR and call routing, notifications, 2FA, WhatsApp, click-to-call, and SIP trunking, the flows your product needs.
Port numbers with FastPort, dual-run on both providers, cut traffic over in phases, and keep a rollback path at every step.
Multi-region, observability, per-minute and per-message cost-optimization, and your team owning the integration and the numbers.
The result delivers the same calls and messages, at a cost you control, on infrastructure you own.
Move voice and messaging off Twilio to Telnyx with TeXML and FastPort, cutting the per-minute and per-message bill, with no downtime.
Click-to-call, IVR, call routing, recording, and conferencing on the Telnyx Voice API and Elastic SIP Trunking.
SMS/MMS, WhatsApp, and notifications, with 10DLC registration and deliverability tuned so messages land.
Connect your PBX or platform to Telnyx Elastic SIP Trunking, with global numbers and porting.
Real-time voice agents on Telnyx Inference, where the co-located LLM keeps the voice loop under a second. Full call-agent builds pair with our AI call agent work.
Cut a climbing telephony bill with routing, channel, and config tuning on Telnyx's owned network.
Twilio is the easy default and the expensive one. The question is whether the per-minute and per-message bill still makes sense, and who owns the telephony layer. Here is the split.
Right when telephony is core to how you reach customers: a first plan in 2–3 weeks.
Telnyx wired into your product end to end: Voice, Messaging, SIP, Verify, compliance, deployed. You own the code and the account.
Move onto Telnyx with TeXML flow mapping and FastPort porting, no downtime, flows and numbers preserved.

Telnyx usage (per-minute, per-message) is billed by Telnyx at their rates, no markup from us. We forecast it, and where a migration cuts it, we show you the math first.
Before any build or migration, we will check your setup or model the move.
Competitor analysis, core feature definition, monetization modeling, and a full launch blueprint — delivered within a week. Written by engineers who'll build what they plan.
An independent review of your system's technology choices, structural components, and workload fit — with a plain verdict on what's working, what's a liability, and exactly what to change to reach your goal. Delivered within a week.
A full audit of your code with every issue documented, evidenced, and located — exact file, exact line. Plus a system architecture review and a prioritized fix roadmap. Not a consultant's opinion. A case file. Delivered within a week.
A specialist review of your video or streaming product covering latency, media server architecture, WebRTC, playback reliability, real-time chat, and scalability. Every finding is specific, located, and fixable. Delivered within a week.
We have built voice and messaging for 20 years, on Telnyx and across the CPaaS and SIP world, so our advice on staying versus migrating is grounded in what we have shipped.
Two decades of voice, messaging, VoIP, and SIP.

What is Telnyx development?
Building voice and messaging into your product with Telnyx's APIs: Programmable Voice and Elastic SIP Trunking, SMS/MMS and WhatsApp, Verify, number porting, and Telnyx Inference for voice AI, plus the compliance, deliverability, and cost controls that make them work in production, and migrating you from another provider when that is the right move.
Which Telnyx products do you work with?
Voice API and Elastic SIP Trunking, Messaging (SMS/MMS/10DLC/WhatsApp), Verify and Number Lookup, Global Numbers and FastPort porting, Wireless/IoT SIM, and Inference / Voice AI. We integrate the products your use case needs across web, iOS, Android, and your backend.
Should I migrate from Twilio to Telnyx?
Often it pays off. Telnyx owns its network, so voice and messaging typically cost about half Twilio's list rates, and TeXML runs your existing TwiML call flows with minimal rewrite. We model your Twilio bill against Telnyx and show the saving before you commit.
How much cheaper is Telnyx than Twilio?
It depends on your mix, but Telnyx lists outbound voice around $0.002 per minute against Twilio's roughly $0.014, and messaging at roughly half the per-message rate, because Telnyx owns and operates the network instead of reselling. We forecast your specific saving in the audit.
How does a Twilio-to-Telnyx migration work?
In phases. We map your TwiML flows to TeXML, port numbers with FastPort, dual-run on both providers, cut traffic over gradually, and keep a rollback path at every step, so there is no downtime and no lost messages.
Can you port our phone numbers?
Yes. We port your numbers to Telnyx programmatically with FastPort, plan the cutover around your traffic, and keep the old provider live until the port completes, so calls and texts never drop.
Can you build voice AI on Telnyx?
Yes. Telnyx Inference co-locates the LLM with the telephony network, so a voice agent's transcription, model, and speech loop stays under a second end to end. For a full call-agent build, see our AI call agent development page; Telnyx is the telephony and inference layer underneath.
Is Telnyx HIPAA and 10DLC compliant?
Telnyx supports compliant workflows, but compliance depends on how you build. We handle 10DLC registration for US SMS, STIR/SHAKEN for voice, HIPAA patterns for regulated comms, and opt-in/consent, so your calls and messages are compliant and deliver.
Telnyx or Twilio, which should we use?
Twilio has the bigger ecosystem and is fine to start on; Telnyx is the lower-cost, lower-latency owned-network alternative and is straightforward to migrate to with TeXML. We build and run both, so we will tell you honestly which fits your volume, regions, and roadmap.
What does it cost and how long does it take?
A cost-and-migration plan or integration plan is about 2–3 weeks from $3K; a production build or migration about 6–10 weeks from $16K; a scale or multi-region project about 10+ weeks from $32K. Telnyx usage is billed by Telnyx at their rates.
