Outbound routing you can actually inspect
A-Z termination with quality tiers you choose per destination, route metrics published in the console, and no silent downgrades when our margin gets thin.
Pick the trade-off yourself, per destination
Every wholesale carrier runs least-cost routing. The difference is whether you can see what it decided and why.
NexDial offers tiered termination. For customer-facing calls where answer rate and audio quality decide the outcome, choose premium routes with direct interconnects and tight quality floors. For destinations where cost leads and the call is transactional, choose standard. You set the tier per destination, and you can change it whenever your priorities change.
Route selection is constrained by quality, not merely reported on afterwards. Each destination carries ASR, ACD and MOS thresholds; a route that falls below them is withdrawn from rotation automatically and re-tested before it returns. Because we hold diverse interconnects per destination, that withdrawal means another carrier rather than a fast-busy.
What we will not do is refile, re-originate or misrepresent jurisdiction to shave a rate. Those practices are prohibited on our own network, and they are the principal reason caller identity gets stripped in transit elsewhere.
- Selectable tiers. Premium or standard per destination, switchable from the console.
- Quality-gated selection. Cheaper routes are only used when they clear the destination quality floor.
- Published route metrics. ASR, ACD and MOS per route, visible to you rather than on request.
- Signed outbound. STIR/SHAKEN attestation based on verified number ownership.
- No refiling. We never disguise jurisdiction or re-originate to lower a rate.

What customers ask
Premium routes are direct interconnects with tighter quality floors and stricter CLI handling — they cost more per minute and deliver higher answer rates with cleaner caller identity. Standard routes accept more intermediaries in exchange for a lower rate. Both are published with their real metrics; we do not label a wholesale path as premium.
Because the metrics are in your console, per route and per destination, updated continuously. If the route we selected for your traffic changes, the numbers move with it and you can see that happen. Rate and route changes also generate notices in the console rather than arriving as an invoice surprise.
Yes, subject to scoping and to our Acceptable Use Policy. International destinations carry tighter default fraud controls — velocity limits, destination blocking and spend caps — because international revenue share fraud is the most common way a compromised PBX becomes a very large invoice.
The traffic is held and we are alerted, rather than delivered badly and billed anyway. That is a deliberate choice: a call that completes with unusable audio is worse than one that did not complete, because you pay for it and your customer remembers it.
Yes. Authorise several IPs on one trunk, or create separate trunks per switch or per customer if you want the CDRs and telemetry separated. Sub-accounts let you give each downstream customer its own credentials and reporting.
Route a test call before you commit anything
Get started through the contact form, load a small balance and send live traffic down a premium and a standard route side by side. Compare the telemetry yourself rather than taking our word for it.
