Class 4 Soft Switch for VoIP Carriers
ConnexCS is a carrier-grade class 4 soft switch built for VoIP carriers, wholesale VoIP providers, and telecom providers — route smarter, protect margins, and stay in control in real time.
Scale to serious volume with integrated billing, automated payments, recording, and transcription — everything you need to run traffic like a modern carrier.
Carrier-Grade Tools to Run Traffic at Scale
Built for class 4 soft switch operations — optimize routes, margins, and customer experience in real time.
High-Volume Call Handling
Run thousands of concurrent channels with steady quality, low jitter, and carrier-grade reliability.
Intelligent Routing Controls
Steer traffic by cost, quality, and geography with route scoring, policy controls, and fast failover.
Automated Billing and Invoicing
Turn CDRs into accurate invoices, apply markups, and automate payment workflows end to end.
Profit Margin Management
Set route-level margins that hold steady as rates move — and keep profitability predictable.
Global Server Footprint Where You Need It
Choose SIP and RTP locations across our global network to reduce latency and keep quality consistent. Regional routing rules help keep traffic local and compliant.
Measured Growth You Can See
After migrating operations, the carrier scaled from 6,800 to 52,000 channels in 8 months — powered by automated routing, fraud controls, and elastic capacity.

Demand-Driven Feature Delivery
The roadmap starts with real carrier stories. A challenge surfaces, a request lands, and the community rallies. We listen, we validate, and we ship what moves the needle.
Requests stay public, trackable, and vote-driven — so the highest-impact work rises fast and stays transparent.
Note: Demand‑driven feature development is free. Urgent, customer‑specific requirements can be prioritised and delivered for a fee.
