Contact centers at scale
Thousands of concurrent agents - zero dropped calls.
Example workflow
10k concurrent calls → routed across 4 carriers → live MOS monitoring → automatic re-route on degradation.
Platform · Tier-1 Carrier Infrastructure
The backbone, already wired in.
Sonaira Connect runs on Tier-1 carriers, redundant routes, and a global number footprint - so voice, SMS, and high-volume communication just work, everywhere.

The idea
Infrastructure is the unfair advantage.
Globally local
Numbers, routes, and PoPs in 30+ regions - voice quality stays carrier-grade.
Redundant by default
Multiple carriers per route. Failover happens before you notice.
Built for volume
Engineered for millions of concurrent calls and messages - no throttles.
How it works
Quality is a design decision.
- Step 01Tier-1 ingress
Direct interconnects with Tier-1 carriers - no resellers, no degradation.
- Step 02Smart routing
Every call picks the best route based on quality + cost + region.
- Step 03Live failover
If a carrier degrades, we re-route mid-attempt - without a dropped call.
- Step 04Always observable
Live PDD, MOS, ASR metrics surface in your dashboard.

Questions, answered
How Carrier Infrastructure works.
Yes - direct interconnects with Tier-1 carriers in every region we operate, with our own SBCs and routing logic. Not a reseller of someone else's network.
