Key features

Built to reduce manual operations while giving admins full control of routing and activation.

Route approval workflow

Customers can request routes. Admins approve, reject, or keep routes pending — without direct back-and-forth.

Company verification (KYC)

Identity validation before enabling premium routes to protect suppliers and reduce fraud.

Operator console

Multi-operator roles and permissions, analytics, monitoring, and operational controls.

Massive scale media handling

RTP clusters keep media load off signaling nodes and allow geo-distributed deployments.

IP Whitelisting

Customers register IPs for secure access and clean onboarding.

CPS/CC Controls

Per-customer limits, protection, and traffic shaping.

Extensible Modules

Custom features, integrations, and payment gateways on request.

Marketplace module

Build your own VoIP marketplace — sellers and buyers can publish, request, and transact online under admin governance.
