Number provisioning

Order, configure and manage local, geographic and freephone numbers directly within the platform. Full details on coverage and number types are on the Numbers page.

Carrier-grade routing

Platform-side routing logic selects the optimal voice path for every call, based on quality, destination and your configured preferences.

Security & GDPR

Voice media is protected by SRTP, with TLS in transit and AES-256 at rest. The platform operates under an ISO/IEC 27001:2022-certified information security management system, with GDPR-compliant data processing within the European Union.

High availability

Voice services run under a 99.95% monthly availability SLA, on two Tier-III data centres in Frankfurt.

APIs and integrations

A public Voice REST API and real-time webhooks deliver call events directly to your systems, so telephony connects to your existing software rather than sitting beside it.

Voice quality

Round-trip latency under 50 ms, engineered for real conversations – including AI-driven ones.

Multi-country service lines connected to your existing contact-centre software, so expansion into new markets never means a new telephony project.
