Carrier · Transport · Billing
The bridge between your carrier and your voice operations
FlowCall is the connectivity layer that links your carrier routes, high-frequency SIP transport, and real-time billing — so you focus on traffic, not infrastructure.
One intelligent layer. Three systems connected.
We do not replace your carrier or your network — we unify them with metering, routing control, and financial clarity.
Your Carrier
Keep your existing carrier contracts and PSTN routes.
FlowCall Bridge
Authorization, routing logic, and session orchestration.
High-Frequency Transport
Low-latency SIP delivery built for volume and uptime.
Billing Engine
Per-second or per-minute metering with live balance control.
Carrier-grade handoff
Seamless interconnection between your upstream carrier and downstream voice traffic — without rebuilding your stack.
Built for volume
Engineered for operators who move high-frequency call traffic and need consistent, predictable routing behavior.
Billing that follows the call
Every completed session is measured, rated, and reflected instantly — transparent packages, no surprises.
