For teams scaling low-latency AI voice, going direct to CLEC carrier has direct reliability and flexibility advantage. Your AI connects to OpenAI, Elevenlabs, or any model you’re already running on carrier infrastructure that owns the path, not an IP overlay that borrows it.

“Instead of providing us with a standard support model with boilerplate language and processes, Bandwidth really came to us and tried to understand what our requirements were for a partnership to make this successful as possible, and that makes all the difference.”
Caroline Coles, Director, Messaging Strategy & Operations
Migration is an endpoint swap, not a rebuild
You aren’t rebuilding. You’re repointing. Bandwidth’s APIs map closely to what your team already uses: keep your application logic, swap your endpoints. Our onboarding and porting experts move existing numbers, 10DLC, toll-free, and short code registrations so your operations don’t start from zero. Start on Bandwidth Build with no app, no downtime, no risk.
Frequently asked questions about Bandwidth vs. Telnyx
An IP network and a PSTN network are not the same thing. Bandwidth does both, but the distinction matters more than most providers will tell you.
Bandwidth is a CLEC (a Competitive Local Exchange Carrier) licensed under the US Telecommunications Act of 1996. That’s not a marketing claim. It’s a regulatory designation that requires direct interconnection with the PSTN at the local exchange level, under FCC oversight and state-level certification in every market we serve.
CLEC designation is what lets Bandwidth connect directly with carriers like AT&T without a middle man, and our scale is what makes this meaningful.
Telnyx takes a different approach. Their Private IP network routes calls efficiently between data centers, but to actually deliver a call, it still needs to reach an end carrier. That last step goes through a third party.
Bandwidth owns and operates its own IP network too. The difference is what sits beneath it. Because we’re also the underlying PSTN carrier, a call on the Bandwidth network never has to leave it.
An IP backbone moves data between data centers. CLEC status means you own the connection into the telephone network itself—which is where voice AI calls live and die.
Bandwidth doesn’t compete on the lowest per-minute rate in Voice API pricing. We compete on what a minute of your call actually delivers: owned PSTN infrastructure, carrier-grade quality, Signature Support, and compliance readiness built in.
Where billing granularity matters: Bandwidth bills voice in 6-second increments, while Telnyx’s standard Voice API bills in 60-second increments. On short calls that are common in AI agent workflows like AMD-screened calls and IVR exits, 6-second billing compounds into real savings. Ask your rep about volume-based pricing for your specific call pattern.
Both include 24/7 support. The difference is what happens after you pay. Bandwidth includes Signature Support free for every customer, with >95% CSAT and in-house network engineers who can diagnose and fix issues directly because they operate the network. Signature support connects you through phone, email, and chat. Full details here.
Public reviews of Telnyx cite post-sale friction—provisioning delays, verification hurdles, and slow ticket resolution at the self-serve tier.
Both support media streaming and WebRTC. Bandwidth’s advantage for real-time AI is the owned PSTN path: fewer hops between your agent and the customer, private routing between POPs, and the SIP URI Ingress + SIP REFER combination that lets an agent transfer out and exit the call flow cleanly without holding both call legs. Bidirectional Media Streaming forks live audio to any AI tool—OpenAI, Deepgram, LiveKit, or your own model.
Bandwidth’s APIs map closely to what most teams already run, so migration is closer to an endpoint swap than a rebuild—keep your application logic, repoint your endpoints. Dedicated onboarding and porting experts handle moving numbers and 10DLC, toll-free, and short code registrations. Start free on Bandwidth Build.
Yes. Bandwidth’s network reaches 65+ countries and territories, including full PSTN replacement in 40+, National Operator status in 30+, and messaging in 120+. Plus our global coverage includes our regulatory know-how and in-country expertise, so our teams can support your expansion.
All transactions through Bandwidth REST APIs are secured using TLS. Bandwidth is ISO 27001 and SOC 2 Type II certified, with a formal Information Security Team and a 24×7 SOC for real-time monitoring across production environments. WebRTC connections are DTLS/SRTP encrypted by default—mandatory at the protocol level.
Yes. Bandwidth’s voice APIs connect via SIP trunking, REST API, or direct integration across the contact center stack. Bidirectional Media Streaming brings live audio to any AI orchestration layer: OpenAI, Deepgram, LiveKit, or a custom model, without locking you into any specific provider. If your team is running a CRM, CCaaS platform, or custom call routing logic, our onboarding engineers work with your existing architecture.
