Softtop's wholesale voice page explains what wholesale voice is — the bulk buying and selling of call termination and origination minutes between telecom operators — and how it differs from retail VoIP, which is priced per seat rather than by volume. It defines A-Z termination as the ability to complete calls to virtually any destination worldwide through direct interconnects or Tier 1 carrier partnerships. The page identifies who uses wholesale voice: carriers and resellers filling network gaps, call centers and BPOs running high-volume campaigns, OTT platforms and CPaaS providers embedding voice into their own software, and multi-site enterprises consolidating international calling. It breaks down how wholesale voice pricing works, comparing per-minute billing (pay for minutes used, best for variable volume) against per-channel billing (a flat fee for fixed simultaneous call paths, best for predictable high-volume traffic), and explains least cost routing (LCR) as the automated process of selecting the cheapest available path that still meets a minimum quality threshold. A dedicated section contrasts CLI routes, which preserve caller ID for higher trust and answer rates, against Non-CLI routes, which are cheaper but carry a higher risk of being blocked. Quality, compliance, and fraud protection are covered through STIR/SHAKEN call authentication and FCC 214/499 registration, the risks of unauthorized grey routes, and International Revenue Share Fraud (IRSF) monitoring. A buyer's guide lists six criteria for choosing a provider — network reach, quality metrics, compliance credentials, pricing transparency, support model, and onboarding speed — plus five key questions to ask before signing a contract. The page closes with client testimonials, an eight-question FAQ, and a call to request a custom rate quote.
