SIP Termination
Send us your traffic. We land it — clean.
Hadlo’s wholesale SIP termination moves your outbound voice traffic across vetted, high-quality routes and lands it on the PSTN cleanly — no dropped audio, no one-way media, no surprise short-duration billing. We built the platform for legitimate conversational traffic, so your ASR and ALOC stay where they should be.
Every call is rated dual-leg and jurisdiction-aware: interstate, intrastate, or local is derived from a real LERG table, and ported numbers are dipped independently on both the calling and called number. That means the invoice you get at the end of the month reconciles to the traffic you actually sent — the single biggest predictor of a termination partner you won’t spend your quarter disputing with.
Least-cost routing runs across multiple vetted carriers with automatic failover, so a soft route re-routes in real time rather than eroding your completion rate. Per-trunk CPS and concurrent-call controls keep your capacity predictable, and STIR/SHAKEN attestation is applied on every call for full downstream traceability.
