Wholesale VoIP Routes

Wholesale VoIP Routes for Carriers, Resellers, and Contact Centers.

Q: What is the difference between CLI and non-CLI routes?

CLI routes preserve the original caller ID end-to-end, which gives higher completion rates and trust. Non-CLI routes strip or randomize CLI to lower cost — suitable for bulk dialing but not for regulated industries or business-critical calls.

Q: What are A-Z VoIP routes?

A-Z routes are wholesale termination contracts that cover every destination globally under a single rate sheet. You get one provider, one invoice, and one operational relationship instead of managing multiple regional vendors.

Q: How does Teloz measure route quality?

We track ASR, ACD, NER, PDD, MOS, and SDC in real time per destination. Customers see the same numbers we use internally and get automatic alerts when any KPI breaches threshold.

Q: Can I use multiple Teloz routes with least cost routing?

Yes. Teloz exposes per-destination tier pricing so you can run LCR across our Premium, Standard, and Economy lanes, or combine Teloz with other carriers in a multi-vendor LCR engine.

Q: Do you support short-duration call traffic?

Yes. We offer billing increments from 1/1 (per-second) for short-call use cases like SMS verification and IVR dial-out, up to 6/6 and 30/30 for traditional voice traffic.

Move every call through premium CLI routes, A-Z coverage, and direct Tier-1 interconnects — monitored in real time on the Teloz wholesale routing platform.

Why Routes Decide Your Margins

What commodity routes cost you every month

Three silent margin killers that compound across millions of minutes — and why the carrier you choose determines whether you catch them.

Hidden surcharges

Short-duration call fees and False Answer Supervision silently erode margins before you see it in CDRs.

Broken caller ID

Inconsistent CLI delivery fails downstream IVRs, fraud filters, and contact center scoring.

Quality complaints first

Route degradation reaches your customers before your dashboards catch it — churn follows.

ASR lift

on a million-minute month

is the difference between profit and a customer churn cycle.

Teloz solves this with direct interconnects, classified route tiers, transparent KPIs, and a routing engine that swaps degraded paths before your traffic feels it.

Tier-1 Interconnects

Direct Interconnects and Tier-1 Carrier Partnerships

Fewer hops mean better quality, lower latency, and cleaner CLI. Teloz invests in direct interconnects rather than reselling third-party routes. According to the ITU-T interconnection standards, direct peering significantly reduces end-to-end latency and improves call quality.
