Core service

SIP trunking that respects your time

Carrier-grade voice on our own SBC infrastructure, backed by a Bandwidth-powered network — with fraud controls built in, not bolted on. Prepaid self-service or term billing for business accounts.

Two ways to get started

No sales call

Self-Service

Sign up with email and card verification — no charge, the card is just verification — get $5 test credit instantly, pick a local number, and make test calls in minutes. Transparent published rates from $0.02/min pay-as-you-go, prepaid wallet billing, no contracts. Perfect for SMBs, dev/test, and anyone who wants to verify quality before committing.

Business & Wholesale

Committed call paths, CPS, term billing, custom rate decks, and reseller arrangements. We ask volume customers to test on self-service first — then we'll talk numbers that match your traffic profile.
