Premium CLI by default

Wholesale voice, with your caller ID intact.

VoxioTelecom terminates A-Z voice traffic for carriers, ITSPs and call centers. Most of our routes are Premium CLI — the number you send is the number that rings.

Guaranteed CLI

The A-number you send is delivered end-to-end on Premium routes.

Direct interconnects

Tier-1 carrier peering, no unauthorized transit.

Real-time monitoring

ASR, ACD, PDD and CLI-delivery visible per destination.

Route types

Two route classes. Zero ambiguity.

We label every destination clearly. If it says Premium CLI, your caller ID is preserved. If it says Standard, it isn't. No grey routes, no silent downgrades.

  • Contract-grade SLA & reporting

Standard

How it works

Sign up, top up, start terminating — in minutes.

No sales calls, no contracts, no waiting on a NOC engineer. The whole flow — account, billing, SIP trunk, routing — is automated end-to-end.

  1. 01

    Create your account

    Sign up with an email — no confirmation step, no manual approval. Your billing client is provisioned automatically on the switch as you land in the portal.

  2. 02

    Fund with crypto or fiat

    Get a dedicated BTC / USDT (TRC-20 & ERC-20) / ETH deposit address, or pay by card / SEPA / wire. Incoming crypto is watched on-chain and credited to your balance within minutes — no ticket.

  3. 03

    Spin up a SIP trunk

    One click in the portal: IP-auth or SIP digest credentials, TLS 1.3 + SRTP optional. Trunk is live on our SBCs in under 60 seconds, already attached to the Voxio Wholesale rate deck.

  4. 04

    Route & monitor live

    Browse the full A-Z rate deck with Premium CLI filtering, watch CDRs stream in, and use the Health dashboard to see provisioning status, ASR, ACD, PDD and CLI-delivery per destination.

Automation first

A self-service carrier — no tickets, no waiting.

Everything you'd normally email a sales rep about is a button in the portal or an API call: create a trunk, add an IP, rotate credentials, change routing, pull CDRs, top up balance. The platform runs 24/7 without human hand-offs.

We keep engineers on Slack for the moments automation can't handle — a peering escalation, a regulatory question, a custom SIP header. Everything else you do yourself, at 3 AM if you want to.

REST + SIP API

Provision trunks, DIDs, routes and rate lookups programmatically. OpenAPI spec included.

Real-time CDR webhooks

Every call end fires a signed webhook with full CDR — plus optional S3 / SFTP push.

Instant provisioning

New SIP trunk live in under 60 seconds. No manual approval steps for standard requests.

Auto top-up

Set a low-balance threshold. We recharge from your card or credit incoming crypto instantly.

Crypto native

Pay in BTC, USDT (TRC-20 & ERC-20) or ETH. Funds credit in minutes, no wire delays.

Every fiat rail too

Card, SEPA, wire, PayPal. Prepaid by default, postpaid weekly invoicing for approved accounts.

Who we serve

Built for teams where every call has to arrive.

We terminate voice for four types of buyer — each with a different sensitivity to caller ID, price and quality.

Tier-2 carriers & MVNOs

Wholesale A-Z termination with per-destination quality guarantees. Backup routes and NOC escalation included.

ITSPs & UCaaS

White-label termination for SIP trunking products. Premium CLI ensures your customers' outbound identity is preserved.

Contact centers

Outbound dialing with reliable local presence via genuine A-number delivery. STIR/SHAKEN attestation on US calls.

SaaS platforms

CPaaS providers, notification platforms, and AI voice apps. Programmable routing with per-second billing.

Quality you can measure

We publish the numbers other carriers hide.

Every customer gets a live dashboard showing per-destination Answer-Seizure Ratio (ASR), Average Call Duration (ACD), Post-Dial Delay (PDD) and — the metric nobody else shows — the percentage of calls where the original A-number reached the terminating handset.

CDRs are streamed in real time via webhook, or pulled hourly via API and SFTP. RADIUS accounting available for legacy integrations.

What buyers say

Trusted by carriers that had run out of patience with grey routes.

"We tested seven wholesale carriers over three months. VoxioTelecom was the only one where the A-number we sent was still on the phone when the customer picked up."
Head of Voice, Nordic Tier-2 carrier
"The rate deck literally says 'Premium CLI' or 'Standard' next to every prefix. That transparency alone saved us weeks of trap-call testing."
CTO, French ITSP
"We signed up on a Tuesday evening, funded with USDT, and had traffic on a live trunk before midnight. Zero emails exchanged."
Voice Product Manager, EU CPaaS
FAQ

Questions carriers ask us on day one.

What exactly makes a route 'Premium CLI'?+

It means the P-Asserted-Identity and From-header you send are delivered unchanged to the terminating operator, contractually enforced by our upstream partners. We audit delivery continuously via test calls.

Do you use grey routes?+

No. Every route in our rate deck is explicitly labelled. If we cannot guarantee CLI on a destination, it is marked Standard — never sold as Premium.

How is billing calculated?+

Per second after the first second. No connection fee, no rounding. Prepaid (wire, card, USDT, BTC, ETH) or postpaid with weekly invoicing for approved accounts.

Can I auto top-up with crypto?+

Yes. Set a low-balance threshold in the portal and we auto-charge your card or credit incoming BTC / USDT (TRC-20 & ERC-20) / ETH deposits within minutes — no interruption to live traffic.

What's your minimum commitment?+

None. Start with a test trunk, scale when the quality proves itself. We don't lock customers into volume commitments.

Can I split traffic across route classes?+

Yes. Route per destination prefix, per source trunk, or via a custom SIP header. Notifications on Standard, sales calls on Premium — same interconnect.

Is the platform self-service?+

Fully. Create trunks, add DIDs, top up, download CDRs and change routing without waiting on a sales rep. Our engineers are on Slack when you want them.

Do you support STIR/SHAKEN?+

Yes. Attestation A on US and Canadian Premium CLI routes for verified caller identities. We are a fully registered US voice service provider.
