Every call. Five reliable steps.
From SIP INVITE to CDR archive, your traffic moves through a deterministic pipeline engineered for sub-second decisions.
Originate
Call enters via your SIP trunk, validated against your IP allowlist & TLS.
Authenticate
STIR/SHAKEN signs the call and assigns an attestation level (A/B/C).
Best-route
LCR engine picks the optimal Tier-1 path on ASR, MOS, and price weights.
Failover
If the primary route degrades, traffic instantly hops to the secondary peer.
Terminate
Carrier delivers the call. CDR + media metrics stream back to your portal.

What you get when the carrier is the carrier.
Direct routes — no middlemen.
We peer directly with Verizon, AT&T, T-Mobile, BT, Deutsche Telekom and 40+ other Tier-1s. Calls get the shortest path, lowest latency, and the best rates — without resold capacity.
STIR/SHAKEN, TRACED, & CLI integrity.
Every outbound call is signed with A-level attestation. We block spoofed CLIs in real time, file your TRACED Act robocall mitigation plan, and ship CDRs that meet FCC retention rules.
Humans on the line, 24/7.
Our US-based NOC watches every route around the clock. Routes drift, CLIs get blocked, peers go dark — we open the ticket before you do, and our SLA backs the credit.
Plug in with SIP, REST or SDK.
Provision a trunk in 90 seconds. Use raw SIP, our REST API, or our typed SDKs for Node, Python, Go, and PHP. Zero proprietary protocols, zero vendor lock-in.
Wholesale voice partners scaling on Teloz.
From resellers to BPOs to outbound dialers — Tier-1 voice, day-one.
“Switching our outbound voice to Teloz cut our per-minute spend by 38% and ASR climbed 6 points the same week.”
“We tested four wholesale carriers head-to-head. Teloz had the lowest PDD and the only NOC that called us first when a peer drifted.”
“STIR/SHAKEN A-level attestation alone moved our answer rate from 41% to 49% on cold-call campaigns. The math wrote itself.”
“Interconnect was live in three business days. The portal showed our first CDRs streaming in before our SIP engineer's coffee was cold.”
