SIXTEEN YEARS OF VOICE.
BUILT FOR TODAY'S DIDs.
We started in 2010 as a wholesale voice carrier and grew through global interconnects, fraud intelligence and an FPaaS platform. In 2022 we paused, rebuilt, and re-emerged in 2024 as an AI-driven DID provider — the same engineering DNA, now focused on two-way voice at scale.
- 2010
Foundation
Launched as a wholesale international voice provider with four carrier interconnections, 20 million annual minutes and approximately €500,000 revenue.
4 interconnects · 20M min/yr - 2011
Regional Expansion
Established direct routes across Europe, the Middle East and Africa. Reached 35 carrier partners, 150 million annual minutes, €3 million revenue and first positive EBITDA.
35 partners · €3M revenue - 2014
Global Voice Network
Deployed proprietary routing and billing infrastructure, opened two international points of presence and exceeded one billion annual voice minutes. Revenue reached double-digit millions with a 10% EBITDA margin.
1B+ min/yr · 10% EBITDA - 2016
Communications Platform
Added DIDs, SIP trunking, number portability and enterprise voice APIs. Connected with more than 150 operators across 50 countries.
150+ operators · 50 countries - 2018
Fraud Intelligence
Created an internal real-time fraud-detection engine after reducing the company's own voice-fraud losses by 80%. Began processing more than one billion signalling and call events per month.
80% fraud loss cut - 2020
FPaaS Launch
Launched the fraud engine as a cloud-based FPaaS product for operators, MVNOs and communications platforms. Awarded top revenue increase for a selected Tier-1 operator in its history.
Tier-1 record revenue - 2022
R&D Reset
Paused to begin an intensive R&D process for the next-generation DID platform — rebuilding provisioning, routing and capacity management from the ground up.
Next-gen DID R&D - 2024
AI-Driven DID Platform
Introduced an intelligent DID platform supporting two-way inbound and outbound voice, automated number provisioning, smart routing, real-time capacity management and AI-assisted service optimization.

READY TO SCALE YOUR
VOICE INFRASTRUCTURE?
Start provisioning in minutes. Our technical sales engineers are ready to discuss your high-volume 2-way voice requirements.
WE PAY ON TIME.
NOT SOMETIMES. ALWAYS.
Sixteen years, zero late settlements. NYX-TEL runs a single primary bank relationship with HSBC and a single multi-currency account — since day one. Every cent that moves through us is traceable, reconciled, and independently audited every year.
We pay on time — not "sometimes", not "usually", but always. Partner settlements, carrier invoices, and supplier terms are honored on the agreed date, every cycle, since 2010.
One primary bank — HSBC. One single multi-currency account, held since day one. No fragmented accounts, no shadow ledgers, no moving funds between jurisdictions. Clean, simple, auditable.
The company is audited every year with independently reviewed audited financials. Our numbers are not internal estimates — they are signed off and available to partners and counterparties on request.
BUSINESS-TO-BUSINESS. NO CONSUMER WALLETS.
NYX-TEL sells exclusively to other businesses. We do not sell DIDs or voice capacity directly to end-users or retail consumers — every relationship is a B2B agreement with a verified carrier, operator, or enterprise.
- Bank transfer only — payments are accepted exclusively from businesses and corporates via bank transfer. No consumer cards, no personal accounts.
- Apple Pay & Credit Cards — available as an option when the payer is a verified corporate entity. Consumer-originated card payments are not accepted.
- Corporate verification — every payer is KYC-verified against our registered counterparties before a single DID is provisioned.
Single multi-currency account since 2010. Annual audited financials. On-time settlement, always. We operate the same way with our banking, our auditors, and our carriers — disclosed, verifiable, and consistent.
Redundancy is not an option we bolt on — it is how the platform is built. We run active redundancy across multiple sites, not a single location. Voice, signalling, and provisioning are replicated with geographical redundancy across separated regions, so a failure in one data center does not interrupt a single DID. Failover is automatic, routing is stateless, and capacity is mirrored — carrier-grade availability, end to end.
TROUBLE TICKETS.
ONE ADDRESS. DIRECT TO THE NOC.
For any trouble ticket — call quality, routing, capacity, porting status, or a live incident — send the details to our Network Operations Centre. Every ticket is logged, tracked, and routed directly to the engineers who run the network. No helpdesk triage, no first-line gatekeepers.
Include your DID(s), affected number range, SIP URI, timestamp (UTC), and a short description of the issue. We acknowledge every ticket and respond against published SLA targets.
WHO WE ARE. IN FULL.
NYX-TEL operates as a fully disclosed, registered entity. No shell companies, no hidden ownership. Our legal identity, registered office, and verification credentials are published here for every customer, partner, and regulator to inspect.
