Wholesale VoIP Termination & Rates
A-Z voice termination for carriers, VoIP resellers and high-volume dialers. Direct Tier-1 interconnects, guaranteed CLI delivery, per-second billing and a dated rate sheet issued per account.
Wholesale VoIP is the bulk purchase of voice termination capacity by a carrier, reseller or high-volume business from another provider — priced per minute per destination rather than per user. You are buying route capacity to carry traffic, not seats for staff.
How is wholesale VoIP priced?
Per minute, per destination, against committed volume. US and Canada landline termination sits at a fraction of a cent per minute; mobile termination into some international markets is an order of magnitude higher. The destination mix in your traffic therefore matters far more than any single headline rate.
We do not publish a fixed public rate card, and you should be sceptical of anyone who does. Carrier interconnect pricing moves continuously. A permanent public A-Z price list is either stale or describes one route. Rate decks are issued per account and dated, so you know exactly what you are comparing.
Wholesale VoIP vs SIP trunking — which do you need?
| Wholesale VoIP | SIP trunking | |
|---|---|---|
| Who buys it | Carriers, resellers, high-volume dialers | A single organisation for its own calls |
| Sized in | Minutes and CPS | Concurrent channels |
| Priced by | Per minute, per destination | Per channel, usually monthly |
| Traffic carried | Other people's, resold onward | Your own |
If you are connecting one company's phone system to the PSTN, you want SIP trunking. If you are reselling capacity or carrying third-party traffic, you want wholesale.
What to check before choosing a wholesale VoIP provider
The advertised per-minute rate is the least informative number on a rate sheet. These six items determine what you actually pay and what your answer rates look like.
| Check | Why it matters |
|---|---|
| Per-destination ASR and ACD, not global averages | A 99% global ASR means little if the three destinations carrying most of your traffic sit well below it. Ask for the breakdown on your specific routes. |
| Billing increment | Per-second billing versus one-minute rounding changes your effective cost substantially on short calls. Compare effective rates, not advertised rates. |
| CLI delivery guarantees | Confirm CLI is preserved on the routes you need. Stripped CLI lowers answer rates and creates regulatory exposure in some markets. |
| Post-dial delay (PDD) | High PDD makes calls feel broken before they connect and causes callers to hang up. It is rarely on a rate sheet; ask for it explicitly. |
| Failover behaviour | Find out what happens when a primary route degrades mid-call and mid-campaign. Automatic requalification matters more than the headline rate. |
| Rate sheet change notice | Ask how much notice you get before rates change, and whether committed volume locks a rate for a defined period. |
Why the cheapest rate is usually not the cheapest route
A low per-minute rate on a route with poor ASR costs more in practice, because you pay for failed attempts in wasted dialer capacity and lost contact. Grey routes that strip CLI quote well and answer badly. One-minute billing rounding can make a headline-cheap rate more expensive than a higher per-second rate on short-duration traffic.
Compare effective cost per connected minute, not advertised rate. That single change in how you evaluate quotes removes most bad wholesale decisions.
Frequently asked questions
What is wholesale VoIP?
Wholesale VoIP is the bulk purchase of voice termination capacity by one carrier, reseller or high-volume business from another, priced per minute per destination rather than per user. The buyer resells that capacity to their own customers or uses it to carry their own traffic, so the commercial model is wholesale rates and committed volume rather than a seat licence.
How much does wholesale VoIP termination cost?
Wholesale termination is priced per minute and varies by destination, route quality and committed volume. US and Canada landline termination is typically a fraction of a cent per minute, while mobile termination in some international markets is an order of magnitude higher. Rates change frequently as carrier interconnects shift, which is why providers issue a dated rate sheet rather than publishing a fixed public price list.
What is the difference between wholesale VoIP and SIP trunking?
SIP trunking connects one organisation's phone system to the public telephone network, sized in concurrent channels for that organisation's own calls. Wholesale VoIP sells termination capacity in bulk to carriers and resellers who then route other people's traffic over it. The underlying technology overlaps; the commercial model, volume and billing granularity do not.
What should I check before choosing a wholesale VoIP carrier?
Look at ASR and ACD per destination rather than headline averages, since a strong global average can hide weak individual routes. Confirm CLI delivery is guaranteed on the routes you care about, check post-dial delay, verify billing increments (per-second billing versus rounding up to the minute changes your effective rate materially), and ask what happens to traffic when a primary route degrades.
Do you offer per-second billing?
Yes. Billing is per second with no minimum duration increment. This matters more than it sounds: a provider rounding every call up to a full minute can be materially more expensive on short-duration traffic even when the advertised per-minute rate looks lower.
What is CLI delivery and why does it matter?
CLI (Calling Line Identification) is the caller ID presented to the person receiving the call. Routes that strip or replace CLI produce lower answer rates because recipients are less likely to answer unidentified calls, and in some jurisdictions CLI integrity is a regulatory requirement. Guaranteed CLI delivery costs more per minute and is usually worth it on any route where answer rate matters.
How do I get a wholesale VoIP rate sheet?
Request a current rate deck through the form on this page. Rates are issued per account because they depend on destination mix and committed volume, and they are dated because carrier interconnect pricing moves. Anyone publishing a permanent fixed public rate card for A-Z termination is either quoting stale numbers or quoting a single route.
