What is a Dedicated Voice PBX Platform and how does it work?

Explore How Dedicated Voice PBX Works

The Dialogios Dedicated Voice PBX is a fully isolated, enterprise-grade telephony platform deployed exclusively for your organization. Unlike shared or multi-tenant PBX solutions, each customer receives a standalone voice infrastructure as self-hosted or on-premise solution with dedicated SIP signaling, media processing, databases, and security layers.

Built on modern technological stack and deployed using Infrastructure as Code (IaC), the platform supports inbound and outbound calls, internal extensions, call groups, queues, recordings, analytics, and full API-driven control. It can be deployed on-premise, in private cloud, or public cloud, and in any geographic region to meet performance and data residency requirements.
