Pricing Structure

Why the Deck Rate Is Never the Real Rate

Pricing model (spot, committed, prepaid, postpaid, tiered) and billing increment (1/1, 6/6, 30/30) mechanics are covered in full on our wholesale VoIP minutes page. Here, the focus is what those mechanics do to a real rate sheet — and how to catch it before you sign.

Sample Rate-Sheet Audit
DestinationDeck rateIncrementEffective rate*
US Mobile$0.00356/6$0.0038
UK Landline$0.00211/1$0.0021
Nigeria Mobile$0.018030/30$0.0231

*Effective rate modeled on a 22-second average call duration. The Nigeria Mobile row shows a 28% gap between deck and effective rate purely from 30/30 billing rounding — the kind of gap that never shows up until the first invoice. Run the same math against your own CDRs with the wholesale voice rate calculator.

Route Quality

Route Quality: The Hidden Cost of a Cheap Rate Sheet

The cheapest wholesale VoIP rate providers are rarely the most profitable. A low headline rate that drops your ASR by 8% can erase the savings instantly.

Red flags in any rate sheet
✕No CLI labeling on routes (Premium / Standard / Economy)
✕Missing ASR, MOS, or PDD published per destination
✕Aggressive False Answer Supervision (FAS) clauses
✕High Short-Duration Call (SDC) ratios on tested routes
✕Different routing for test traffic vs production

Provider Comparison FAQ

The short answers.

Common questions from carriers, resellers, and contact centers shortlisting wholesale VoIP rate providers.

A wholesale VoIP rate provider is a carrier or aggregator that sells per-minute voice termination at bulk pricing. Their customers are typically resellers, ITSPs, contact centers, and other carriers that need to deliver outbound calls.

Most providers publish weekly rate updates, with daily updates on volatile destinations. Major rate revisions happen monthly, and contract-bound rates usually carry 7–30 day notice windows.

A-Z providers offer a single contract covering every global destination on one rate sheet. Destination-specific providers focus on regional corridors. Many buyers run a primary A-Z provider plus 1–2 specialists for high-volume corridors.

A Most-Favored-Nation (MFN) clause guarantees that if the provider offers a comparable buyer a lower rate, you automatically get the same price. It protects you from rate creep over the life of the contract.

Standard onboarding takes 3–7 business days, including KYC, credit review, SBC configuration, and test-call validation. Enterprise accounts with enhanced due diligence may take 2–3 weeks.

Transparent rates, carrier-grade quality. No contract traps.
