Anyone can send you a rate sheet. What that document cannot tell you is whether the invoice at the end of the month will reconcile, whether your intrastate traffic is being rated correctly, what happens the night a route goes soft, or whether the provider will still be a clean, well-regarded network to be interconnected with a year from now. Those are the things that actually determine your experience as a wholesale buyer, and none of them appear on the front page of a rate card. Here is what to ask before you commit traffic to a termination partner.
Ask about billing before you ask about rate
Correct billing is unglamorous engineering and the single best predictor of a partner you will not spend your quarter disputing with. The questions are specific, and the quality of the answers tells you a great deal.
- Is rating dual-leg — both origination and termination priced — or single-leg with the rest estimated?
- Is jurisdiction (interstate, intrastate, local) derived from a real LERG table, or inferred from the dialled prefix?
- Are ported numbers dipped independently on both the calling and called number before rating?
- What is the billing increment and minimum duration, and are there per-call connection fees?
If the answers are vague, the invoices will be too. A provider who can explain their rating in detail is a provider whose bills you can trust; one who deflects is telling you where your next dispute will come from.
Then ask about the bad night
Least-cost routing is table stakes; every provider claims it. What separates networks is what happens when a route degrades. Automatic failover around a soft route, real per-route quality monitoring, and a human who can trace a call end to end are what you are actually buying. Ask how failover is triggered, whether you can see ASR and ALOC per destination over time rather than a sampled snapshot, and who you reach when something breaks outside business hours. The answers reveal whether you are buying a rate sheet or a network.
Ask about the company you will be keeping
In wholesale voice, your reputation is partly the reputation of the networks you interconnect with. A provider that mixes clean conversational traffic with high-volume automated dialler traffic is exposing your traffic to the analytics labels and answer-rate damage that follow the bad traffic. It is entirely reasonable to ask a prospective partner what kind of traffic they carry, how they vet their customers, and how they respond to traceback requests. A provider built around legitimate conversational traffic will welcome the question; one who is cagey about it is answering it anyway.
Ask about compliance posture
The regulatory ground under wholesale voice keeps shifting, and a partner who is behind on it becomes your problem. Confirm they are properly listed in the Robocall Mitigation Database, that they sign traffic with their own certificate and make their own attestation decisions, and that they take Know Your Customer and Know Your Upstream Provider seriously rather than treating them as future problems. Compliance is not a cost they are grudgingly absorbing; done right, it is evidence of an operation that will still be dependable next year.
The pattern behind the questions
Every one of these questions is really asking the same thing: is this a network run by people who understand the business, or a rate sheet with a phone number attached? Correct billing, routing discipline, clean traffic, and a serious compliance posture are all expressions of the same underlying competence — and that competence is what keeps trouble tickets in the single digits per year rather than the hundreds.
Hadlo rates every call dual-leg and jurisdiction-aware, monitors quality per route with automatic failover, carries legitimate conversational traffic, and treats compliance as part of the network rather than a bolt-on. If those are the answers you are looking for, talk to us.
