Since 2000, WH Telecom has been the wholesale voice termination partner carriers call when it absolutely has to work. 26 years. 190+ countries. 1.2 billion minutes a year. Still founder-led. Still picking up on the first ring.
Most VoIP termination companies are 5–10 years old. We've been battle-testing routes, catching fraud, and building carrier relationships since the year 2000. That gap shows up in your ASR, your margins, and your 3am outage response times.
Nothing on this platform is theoretical. Every feature was forged from real outages, real fraud attacks, and real carrier demands across two and a half decades of production traffic.
Most LCR engines have months of data. Ours has 26 years of CDRs — billions of calls across 190+ countries. Our ML models don't guess the best route. They know it. Carriers typically see 8–15% ASR improvement in their first week.
We've been catching telecom fraud since before it had a name. 26 years of attack-pattern data powers ML models that detect IRSF, wangiri, and traffic pumping before the first fraudulent call completes.
See every metric the moment it happens — ASR, ACD, PDD, margin, all live. Drill into any CDR. Set custom alerts. No waiting until tomorrow for yesterday's data.
Relationships don't build overnight. We've spent 26 years securing Tier-1 agreements on every continent. No aggregators. No grey routes. Every path is a direct line we built ourselves.
Our infrastructure has survived 26 years of traffic spikes, DDoS attacks, and carrier failures. Scale from 50 to 50,000 concurrent channels. Geo-redundant SBCs failover automatically.
Our NOC engineers have an average tenure of 11 years. They've seen every failure mode, every edge case, every 3am crisis that telecom can throw at you. They pick up on the first ring — 365 days a year. Average incident response: under 15 minutes.
After 26 years and 500+ carrier onboardings, we've removed every point of friction. Most carriers send their first live call within 30 minutes.
One form. No paperwork, no credit card, no sales call. Your SIP credentials are generated instantly — because we learned a long time ago that forcing carriers through hoops loses good customers.
Aim your PBX at our SIP gateway. TLS and SRTP out of the box. We've written integration guides for every major softswitch and PBX — because we've connected to all of them.
Route test traffic to any of our 190+ destinations on our dime. Check ASR, ACD, and voice quality yourself. We don't ask you to trust us — we ask you to verify.
Fund prepaid and ramp at your own pace. Need 50 channels today and 5,000 next month? Done. Our infrastructure has been scaling carriers for over two decades.
No credit card · No contracts · Free test credits included
You can't buy carrier relationships. You earn them — one interconnect at a time, over years and decades. Our network spans 190+ countries because we started building it in 2000 and never stopped.
After 26 years of building integrations, we know exactly what developers need: clean REST endpoints, real-time webhooks, WebSocket CDR streams, and documentation that actually matches the code.

Real results from carriers who switched. No paid endorsements — just operators who found something better and want you to know about it.
"Switched our US termination to WH Telecom — ASR jumped 12% literally overnight. These guys have been at this longer than half the companies in our vendor list have existed. The depth of their network is unmatched."
"Within our first month, FraudGuard caught $47K in IRSF attacks our previous provider never even detected. It's the kind of protection you only get from a team that's been fighting telecom fraud for over two decades."
"First contact to production traffic in under 2 hours. When we hit a routing issue at 3am on a Sunday, their NOC answered on the first ring. Not a bot — an engineer who already knew our setup."
500+ carriers route with us because we earned it — one call at a time, over two and a half decades. See the difference yourself.
