Why providers route through a broker
Standing up wholesale voice and messaging means qualifying carriers, negotiating rate decks, building redundancy, and watching for fraud. A broker carries that weight so your team can stay on your product.
About Jay Kordic and the brokerage model- 01
- One relationship, many networks
- A single point of contact into direct interconnects with multiple tier-1 carriers, instead of chasing and qualifying each one yourself.
- 02
- Routing built for cost and quality
- Least-cost routing and rate-deck management that balances margin against answer-seizure quality, with redundant paths when a route degrades.
- 03
- Fraud and traffic security
- Telecom fraud management and STIR/SHAKEN-aligned traffic monitoring sit alongside the routing, not bolted on after a problem.
- 04
- Founder-led since 1998
- Jay Kordic has spent 28 years helping providers interconnect. The desk you reach is the one that has done this work for more than two decades.
