Praytec Dialcortex

Intelligent voice infrastructure for modern businesses.

Combine Cloud PBX, SBC, softphones, contact center, and AI voice agents in one communications platform — from everyday business calling to large-scale conversation automation.

Architecture

Five layers: a secure edge, a private PBX core, then AI conversation.

Praytec Dialcortex separates SIP security, the phone runtime, and conversation automation. The PBX is not exposed to the internet. AI, the dialer, and human agents share the same trunks and recording trail.

Three planes: signaling and media stop at the SBC, call control lives in the private PBX, and conversation runs in AI or with an agent. Campaigns connect only calls that a person actually answers.

AI Voice Agent

Automate repetitive calls — keep them human-like.

Praytec Dialcortex places AI on real telecommunications infrastructure. Voice agents understand intent and context, reply naturally, take actions in business systems, then hand off to people when the conversation needs it.

Built for verification, appointments, lead qualification, telemarketing, surveys, and routine customer service — including multilingual conversations for regional markets.
