What our wholesale partners are saying.✦

How carriers, resellers, and operators are scaling on the network — verified outcomes from the account review process.

DT

Director of Telecom

Multi-Brand UCaaS Reseller

5.0

“We consolidated three vendors — voice, DIDs, and SMS — into one TKOS account. One contract, one NOC, one CDR feed. The operations team got their evenings back, and our African ASR jumped 18 points in the first month.”

Wholesale VoIP
OM

Operations Manager

Wholesale Voice Carrier

5.0

“We've been sending US and African traffic for the last six months. Call quality is excellent with stable CLI delivery and very low PDD. The support team responds inside ten minutes — and that includes weekends.”

A-Z Termination
SM

Sales Manager

International VoIP Reseller

5.0

“As a wholesale VoIP provider ourselves, we rely heavily on strong carrier partnerships. This network has been consistent — high-quality routes, stable CLI presentation, and Africa-direct connections we can't get from US-based providers.”

Africa-Direct
VP

VP of Network Operations

Outbound Contact Centre

5.0

“The free trial sealed it for us. We measured the routes for two weeks before committing — and eight months later the rates haven't quietly drifted upward like they did with our last provider. That alone made the switch worth it.”

FAQ

The service is built for telecom carriers, resellers, and high-volume call centres, in contrast to retail VoIP, which targets individual end users with bundled features and fixed pricing.
