International voice looks simple from the outside: a call goes in, a call comes out. Behind it, every route is a decision about quality, cost and risk. Choose the wrong partner and you pay for it in failed calls, unhappy customers and, worst of all, fraud that appears on the invoice weeks after the damage is done.

US Matrix Voice is built for carriers and enterprises that cannot afford that trade-off. We terminate international traffic over direct and premium routes to strategic and hard-to-reach destinations, with fraud control that acts in real time on every call.

## A wholesale partner on your side

Since 2003 US Matrix has carried wholesale voice for operators around the world. Our role is simple: deliver your traffic with the quality your customers expect and protect your margin while doing it.

> Your wholesale provider should be your first line of defense against fraud, not the last one to find out.

What you get:

- **Direct and premium routes** to 250+ carriers, including 35+ mobile operators reached directly.
- **Every type of traffic**: international long distance, international toll-free, calling-card and prepaid.
- **Fraud control in real time**: limits by country, network, number or range, for both A and B parties, that track, alert and block during the call, with no waiting for post-CDR analysis.
- **Alerts where you are**: email, SMS or voice notifications to the contacts and priorities you choose.
- **SIP and TDM interconnection** and a dedicated account team.
- **24x7 NOC and fraud desk.**

## Who benefits

- **Tier-1 and national carriers** that need reliable termination to destinations outside their own footprint.
- **Internet service providers** that offer voice and want international calling without building international routes.
- **Calling-card and prepaid long-distance companies** whose margins depend on route quality and fraud control.
- **Contact centers** that call customers in many countries and need stable quality at a predictable cost.

## More value from your portfolio

- **Protected margin.** Real-time limits stop fraudulent traffic before it becomes a cost.
- **Fewer complaints.** Better routes mean fewer failed calls and fewer support tickets.
- **One partner for more services.** The same account can add phone numbers, messaging and mobile lines.

## Cross-sell across the US Matrix portfolio

- **DIDs**: local and toll-free numbers in 150+ countries for inbound traffic.
- **SMS**: A2P messaging for verification codes and alerts.
- **US Matrix Mobile**: your own 5G mobile brand, with no network investment.

## How to get started

1. **Technical and commercial call.** We review your destinations, volumes and quality targets.
2. **Interconnection.** SIP or TDM, configured with our engineers.
3. **Fraud rules.** We set limits and alerts by country, network, number and range.
4. **Test traffic.** You validate quality on the destinations that matter most.
5. **Go-live.** Our NOC monitors your traffic 24x7.

## Day to day

Traffic flows over the routes agreed for each destination. Your team receives fraud alerts the moment a limit is reached, and our NOC and account team follow quality and volumes with you.
