Explore our wholesale services
Rate decks, LCR, CDRs — all in the partner portal.
Teloz publishes rate decks, supports LCR ingestion, and provides a portal with real-time CDRs, rate changes, and dispute tooling — all built to meet ITU voice standards for carrier-grade interconnects. Interconnects happen fast — days, not weeks.
Interconnect in days, not weeks.
A typical Teloz interconnect walks through four phases — with a human engineer on every step.
SIP signaling setup
TLS/SRTP where needed, IP whitelisting, and endpoint configuration. Your engineers test against our sandbox.
Test traffic + rate decks
Rate decks delivered in partner-standard formats (CSV, XLS). Test calls validate signaling, media, and CDRs.
Graduated live ramp
Start at a fraction of production traffic — including toll-free number routes. Quality monitored in real time — ramp only when metrics stay green.
LCR + SLA monitoring
LCR input accepted for partners running their own routing. ASR, PDD, and availability tracked against a written SLA.
Wholesale VoIP partners across the US build on Teloz.
From resellers to enterprise carriers, programmable voice at scale.
“We cut post-dial delay in half on the US-East route after moving to Teloz.”
“Interconnect took four business days, not six weeks. The NOC stayed on the bridge until our first million minutes completed cleanly.”
“When a downstream peer degraded at 2 AM, Teloz re-routed automatically and had a ticket open with the upstream before I woke up.”
“STIR/SHAKEN A-level attestation lifted our answer-seize ratio 8% in the first month. Spam-labeled calls dropped and revenue followed.”
The short answers.
Everything partners ask before going live.
Peer with a real carrier. Sign an SLA, not a slide.
SIP trunks, DIDs, toll-free, STIR/SHAKEN — on a US-licensed network with a 24/7 NOC staffed by humans.
