The right trunk for your operation.
Every solution is built on the same carrier infrastructure — FCC-licensed, own STIR/SHAKEN certificate, unlimited channels. The difference is how we configure and support it for your specific workload.
A predictive dialer pushing 500 concurrent channels needs a carrier that can absorb burst traffic without throttling. A call center running inbound queues needs DIDs with clean caller ID reputation and fast failover. A political campaign dialing millions of voters in the final 72 hours needs attestation that does not collapse under volume. A wholesale reseller needs rate decks and direct peering rather than retail features. Each of these is the same product at the network layer — SIP trunks with A-level attestation — configured differently for the workload.
The solutions below map common operator profiles to the SIPNEX configuration that fits. If you already know what you are running, jump directly to the matching card. If you are migrating from a reseller, a CPaaS, or a legacy T1, use the comparison pages to see what changes under a direct carrier. If what you need is not on this page, call an operator — every SIPNEX trunk is bespoke-configured, not picked from a dropdown.
All solutions share the same underlying guarantees: no concurrent channel caps, no per-seat upsell tiers, no quote-gated pricing, transparent published rates, direct A-level STIR/SHAKEN signing, and support from engineers who have run the same platforms you run. We do not rebadge an upstream provider's service with a different name — the carrier is us, and the configuration is specific to your use case.
