A termination route you test before you trust.
Carrier-to-carrier SIP termination into the U.S. PSTN, priced by destination, proven on your traffic before you commit to it.
What you're buying
Domestic U.S. voice termination for carriers, ITSPs, CPaaS platforms, and enterprise call centers — no retail, no residential lines, just carrier-to-carrier traffic routed to completion. You send us SIP; we terminate it to the PSTN and hand back clean CDRs.
How it works
Tell us your traffic.
Volume, destinations, traffic type (outbound dialer, inbound DID, 2FA voice, conversational AI). This shapes which rate decks and which route set we propose for your pilot.
Run the pilot.
Every relationship starts with a defined route set and a fixed window — typically 48 to 72 hours. We're not asking you to take the quality of the route on faith.
Review the numbers together.
ASR, ACD, PDD, and clean CDRs with no false answer supervision — measured on your actual traffic, not a demo account.
Sign and scale.
Once the pilot clears, we move to a standard commercial agreement: rate deck, credit terms, and billing increment set in writing before the first production minute.
Technical details
SIP, carrier-to-carrier (Class 4). BYOC-friendly — this is built for platforms that already own their application layer and need a termination partner, not a full stack.
Standard 1/1 or 6/6 second billing, set per agreement.
G.711 for quality-sensitive traffic; G.729 available on cost-sensitive routes where compression is acceptable.
Every call carries our own STIR/SHAKEN attestation — signed with our certificate, not borrowed from an upstream. See Compliance & Trust for how attestation decisions are made.
Velocity caps, Do-Not-Originate enforcement, and geo/destination blocking run at the network edge, before a call completes.
ASR, ACD, PDD, NER, MOS, jitter, and latency are tracked by destination, not just in aggregate — ask about dashboard access as part of onboarding.
Commercial terms
New accounts start with a deposit or prepaid balance, consistent with standard wholesale practice — this protects both sides and lets us extend credit terms as a track record builds. Your account team will walk through specific terms once the pilot clears.
Who this is for
- AI voice-agent platforms sending outbound and inbound agent traffic at volume.
- CPaaS and UCaaS resellers looking for a supplemental or redundant U.S. route.
- Nearshore and collections BPOs that need clean CLI and predictable billing on high-volume outbound.
See the segment-specific pages for AI Voice, CPaaS, and BPO traffic.
FAQ
1/1 or 6/6 seconds, agreed in your contract. We don't run a single one-size-fits-all increment across every account.
Yes, for new accounts — standard practice in wholesale termination, where we're contractually on the hook to our own upstream carriers regardless of whether a customer pays on time. Terms are set per account based on volume and history.
We track quality per destination, not just in aggregate, so a degrading route gets caught and reallocated rather than sitting unnoticed inside a healthy-looking average.
Yes — that's the point of the pilot. A defined route set, a fixed window, and pass/fail criteria you can check yourself.
