Five layers. One telephony platform.

The core stack

Numbers, trunking and APIs — every layer tuned for machine-speed conversation rather than human dialling, and available under a single contract, console and invoice.

01Numbers

Global phone numbers in 190+ countries

Provision local, national and toll-free numbers in minutes instead of weeks. Automated eKYC handles the paperwork, and every DID ships with caller-ID control and continuous reputation monitoring so your agents never start a call already flagged as spam.

  • Instant self-serve provisioning with automated eKYC
  • Local caller ID and branded calling where supported
  • Spam-flag monitoring with automatic number rotation

02SIP Trunking

Carrier-grade voice infrastructure at scale

Direct Tier-1 carrier interconnects with regional media edges, so audio takes the shortest path between your agent and the caller. Elastic channels absorb campaign spikes without pre-purchased capacity or monthly minimums.

  • Sub-80ms one-way latency on Tier-1 interconnects
  • 99.999% trunk reliability with automatic failover routing
  • Opus and G.711 with echo and noise cancellation built in

03Voice APIs

Programmable voice APIs with real-time audio streaming

Stream raw call audio over a WebSocket in 20ms frames and pipe it straight into Garuda, Vyas and Kaak — or your own stack. Full call control means your agent can transfer, hold, record, collect DTMF and barge in mid-sentence.

  • Bidirectional media streaming in 20ms PCM frames
  • Barge-in, warm transfer, recording and DTMF capture
  • SDKs for Node, Python and Go with webhook call events

Your voice infrastructure should be the last thing you worry about

Legacy CPaaS was designed for notifications and IVR trees. Local telcos were designed for humans. Neither was designed for an agent that has to think and answer inside a single breath of silence.

How a high-volume voice AI team moved enterprise workflows onto 60db Telephony

Customer story

“We were stitching together three carriers and still losing calls at peak. Moving the transport layer to 60db gave us one API, one invoice, and latency our agents could actually think inside of.”

The infrastructure platform for voice AI builders and integrators

Partner program

Your brand. Your pricing. 60db under the hood.

Run your entire voice business through a single multi-tenant API. You own the customer relationship, the pricing and the product surface — we carry the calls, the carrier relationships and the regulatory load behind it.

Provision customer accounts

Create, suspend and manage tenants through one API. Every sub-account gets isolated numbers, trunks and call records.

Control your own billing

Set your own rate cards and margins per tenant. Real-time usage metering and reconciliation feed straight into your invoicing.

Manage DID inventory

Buy, pool and assign numbers across customers, with automated eKYC and porting handled underneath your brand.

See everything in real time

Call records, quality scores and spend roll up per tenant, so support conversations start with data instead of guesswork.

Questions? We're here to help

Everything teams usually ask before moving their calls over.

60db Telephony is the transport layer underneath voice AI: phone numbers, SIP trunking and programmable voice APIs in one platform. It is built for teams shipping production voice agents — AI startups, contact-centre modernisation projects and enterprises replacing IVR trees with real conversation.

Three things: direct Tier-1 carrier interconnects instead of resold routes, regional media edges that terminate audio close to the caller, and a media path that streams 20ms PCM frames over WebSocket straight into your models rather than buffering whole utterances. The result is a shorter physical path and far less queueing between the caller speaking and your agent responding.

Yes. You can port existing DIDs, bring your own SIP trunk, or run 60db alongside a current provider during migration. On the software side the platform is orchestrator-agnostic — LiveKit, Pipecat, your own stack, or 60db's Kaak, Garuda, Vyas and Smriti models. Nothing about the setup locks your agent logic to our number inventory.

The platform is ISO 27001:2022 certified and SOC 2 Type II audited, GDPR compliant with EU data residency options, HIPAA ready with a BAA available, and aligned with regional data-protection laws. eKYC, consent capture, DNC scrubbing and calling-window rules are enforced at provisioning and call time rather than left to your application.

Every DID is monitored for reputation signals across carrier and handset labelling systems. Traffic is spread across pooled numbers with configurable pacing, local caller ID is used wherever it is permitted, and numbers showing early flag signals are rotated out automatically before answer rates collapse.

The network carries over three million calls a day with a 99.99% completion rate, and channels scale elastically without pre-purchased capacity or monthly minimums. Trunks fail over automatically between carriers and regions, and enterprise accounts get an SLA with a sub-60-minute average support turnaround.
