Route quality first
Routes are graded on ASR, ACD and PDD, not on cost alone. Underperforming carriers get pulled from the LCR table before you notice them — not after you open a ticket.
Wholesale SIP termination · US48 + International A-Z
Minutes that land the first time.
NVA is a wholesale voice aggregator. We do one thing: terminate your SIP traffic on direct, monitored routes at rates you can actually build a margin on.

Why carriers route to us
One service. Held to a carrier standard.
Pricing you can audit
A rate deck with real jurisdictional breakouts, per-second billing after the first six seconds, and no invented surcharges. What the deck says is what the CDR says.
Capacity that holds
Provisioned for burst, not for the average. Campaign traffic, holiday peaks and dialer ramps hit the same switch capacity as a Tuesday afternoon.
What we sell
Termination, by route class.
Every class is available on its own trunk group, so you can weight traffic yourself instead of accepting a blended average.
CLI
CLI / Premium
Caller ID passed end to end on direct interconnects. For traffic where answer rate and audio quality decide the business — support lines, appointment reminders, conversational IVR.
NCLI
Non-CLI / Standard
Cost-optimized routing for high-volume, price-sensitive traffic. Same monitoring, different economics.
US48
US48 Domestic
Interstate, intrastate and indeterminate jurisdictions rated separately, with LATA and NPA-NXX detail on every CDR.
A-Z
International A-Z
Global coverage through vetted upstreams, with mobile and fixed breakouts priced independently rather than blended.
The switch
Built for burst.
Capacity is the part of a wholesale relationship you only find out about at the worst moment. Ours is sized so that your peak is our ordinary.

Getting connected
Four steps to live traffic.
-
Send a traffic profile
Destinations, expected minutes, concurrency and average duration. A recent CDR sample is faster than a form.
-
Get a rate deck
Priced against your actual destination mix — not a generic sheet — usually within one business day.
-
IP auth and test trunk
We whitelist your SBC, you whitelist ours, and you run test calls against every route class before committing.
-
Go live
Capacity set, CDRs streaming, and a named contact who answers when a route moves.
Regulatory posture
STIR/SHAKEN
Calls signed with attestation appropriate to the customer relationship and number verification on file.
Robocall Mitigation
Mitigation plan filed and maintained in the FCC Robocall Mitigation Database.
Traffic vetting
Know-your-customer on every interconnect, with traceback responses handled inside the industry SLA.
