Underlying Carrier vs. Traffic Wholesaler: Why Cheaper Minutes Cost You Answered Calls.

If your dialer's outbound calls are showing up as "Scam Likely" on Verizon, T-Mobile, and AT&T handsets, the problem isn't your script. It's your STIR/SHAKEN attestation level. And if you're routing through a traffic wholesaler instead of an underlying carrier, you're likely locked at attestation B or C — which today's carrier spam analytics treat about the same as an unsigned call from a robocaller.

Here's the actual difference between the two models, and why the wholesale economics quietly fall apart for any contact center that depends on answered calls.

What a traffic wholesaler is

A wholesaler buys minutes in bulk from Tier-1 carriers, marks them up a fraction of a cent, and resells them. They use Least Cost Routing — your call may pass through three intermediate carriers before it terminates. They don't hold FCC LEC authority. They can't sign A-level STIR/SHAKEN because they aren't the originating Local Exchange Carrier. When a call gets dropped or flagged, they file a ticket with their upstream and you wait.

That's the model. It's cheap because it's a middle layer.

What an underlying carrier is

Greenway Communications is a Competitive Local Exchange Carrier — CLEC — authorized in Iowa and New York. We hold FCC Form 499 status and contribute to USF. We sign A-level STIR/SHAKEN attestation in-house because we are the originating LEC on the call. We run US-based SIP trunking with available Tier-1 carrier ICAs and geo-redundant US data center routing — built out against your specific traffic patterns once your demand profile is in hand.

When something goes wrong on a call we originated, there's no upstream to escalate to. We own it.

The math, in fractions of a cent

Per-minute rates aren't a single number. They vary by terminating rate center — your effective cost depends on where your traffic actually lands, not whatever headline figure made it into your sales conversation. Wholesale termination generally lives in the low single-digit fractions of a cent per minute, with the rate moving as your traffic pattern moves.

For customers with the right traffic profile — meaningful volume, a workable Answer-Seizure Ratio, reasonable Average Call Time — Greenway can build a single nationwide fixed-rate deck with NECA-territory carve-outs. That kind of pricing predictability is hard to get from a wholesaler whose own upstream costs are floating.

Run it the other way: if your B-level attestation is sending a meaningful share of your outbound calls to "Scam Likely" — and we expect to see this consistently with offshore BPOs that move to us — the answer-rate gap closes the per-minute cost gap on day one. The cheap minute costs you the connection.

What offshore call centers specifically gain

US LEC backing gives you a regulatory shield. When the FCC, a state PUC, or a carrier compliance team asks where your traffic originates, the answer is "Greenway Communications, US-licensed Exchange Carrier" — not "a wholesaler routing through who-knows-where." That answer is a lot shorter and a lot cleaner.

You also get instant DID provisioning in our rate centers, real-time CDRs through a web portal and API, and engineers who answer the phone when you call them.

What's actually in the package

The per-minute rate is the headline number; it isn't the whole bill. Two items Greenway includes that traffic wholesalers — and most underlying carriers — quietly charge separately for:

• DIDs at $0.00 per month with qualifying volume. Most carriers charge a per-DID monthly fee. Bandwidth's published voice API pricing is a fair benchmark for what the rest of the industry charges. When your traffic clears our volume threshold, Greenway provides DIDs at no recurring cost. That's a real line item off your bill.
• Hosted intermediate IVR — $5 per month flat, unlimited DIDs. Every Greenway customer is offered an intermediate IVR that greets inbound callers, identifies who called them and why, and routes them to alternative contact paths or additional information. One $5/month fee covers an unlimited number of your assigned DIDs. Stock messaging is free; a one-time $25 setup gets you customized messaging.

Two items isn't a long list. That's the point. We don't itemize a wall of optional add-ons because we don't compete on lookalike fees. What you see on the rate sheet is what you pay. The full pricing structure is published — per-minute, DIDs, IVR, and what we won't do.

The bottom line

We are your US voice anchor. We aren't the cheapest minute on the market and we aren't trying to be. We are the carrier whose A-level attestation gets your call answered, whose negotiated Tier-1 ICAs are built around your traffic, and whose engineers own it when something breaks. The DIDs and the hosted IVR are in the package because they should be.

That's the difference between buying minutes and partnering with a carrier.
