Notes from the network.
Straight talk on wholesale voice, routing accuracy, and staying ahead of the FCC.
KYC and KYUP: what’s coming, and why we built for it early
The FCC is moving from ‘signed agreement’ to ‘verified identity’ — for the customers you sell to and the upstream providers you buy from. A look at where the rules are heading and why getting ahead of them is the cheaper path.
Clean traffic is a business advantage: protecting ASR and your reputation
Legitimate conversational traffic is not just the compliant choice — it is the more profitable one. How clean traffic protects the answer rates, attestation, and reputation that determine whether your calls complete at all.
LERG vs LRN: why we dip both numbers, every time
The dialled prefix tells you where a number was born. Only an LRN dip tells you where it lives now. For correct rating and routing, you need both — and you need them on both the calling and the called number.
Choosing a wholesale termination partner: the questions that matter
Rate is the easy part, and the least predictive. The questions that actually determine your experience are about billing accuracy, routing discipline, compliance posture, and who answers when a route goes soft at 2am.
Toll-free for resellers: RespOrg, the 8XX range, and why control matters
Toll-free is one of the most valuable numbers a business can own, and one of the most misunderstood by the resellers who sell it. A practical primer on 8XX availability, RespOrg control, and inbound routing.
The RMD recertification window is a deadline, not a reminder
Miss the annual Robocall Mitigation Database window and you can be removed from the database entirely — which functionally blocks your ability to originate or carry US traffic. Why it deserves an owner, not a sticky note.
A, B, or C: what STIR/SHAKEN attestation really tells you
Attestation is not a quality score — it is a precise statement about what the signing provider actually knew when it signed the call. Read it correctly and it becomes one of the most useful diagnostics you have.
Wholesale SIP termination pricing: how per-minute rates really work
Rate is the easy number to compare and the wrong one to optimise for. Here is a full breakdown of what actually drives your wholesale termination cost — jurisdiction, increments, route quality, and the questions that separate a real network from a rate sheet.
A-Z termination explained: matching route quality to your traffic
Behind a single per-destination rate sits a chain of carriers, each with its own quality — and the route you were sold today may not be the route your calls take next week. A guide to buying international termination well.
US DID numbering: rate centers, LERG, and getting porting right
A US local number looks like a simple string of digits until porting and jurisdiction go wrong. A grounded look at the reference data behind DIDs — rate centers, the LERG, and LRN dips — and how to buy numbering that just works.
