Director of Telecom
Multi-Brand UCaaS Reseller
“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.”
Operations Manager
Wholesale Voice Carrier
“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.”
Sales Manager
International VoIP Reseller
“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.”
VP of Network Operations
Outbound Contact Centre
“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.”
Everything carriers, MSPs, and platform builders need to scope a wholesale VoIP partnership. Can't find an answer? The team is one click away.
Wholesale VoIP termination rates vary by route type and destination. CLI routes — which display a full caller ID — carry a premium over NCLI and CC routes due to higher answer rates and stricter quality requirements. Africa-direct routes are priced competitively versus routes transited through European or US aggregators. Contact us for a full A-Z rate deck tailored to your destination mix and monthly volume.
