Unified Communications

IP PBX & CRM
Integration

Asterisk-powered VoIP networks seamlessly connected with real-time CRM dashboards — SIP trunks, WebRTC agents, and unified customer data in one platform.

The Architecture

Designed for Operational Control

Our VoIP architecture integrates Asterisk IP PBX with custom Node.js middleware, real-time WebRTC endpoints, and unified CRM dashboards — delivering complete call lifecycle management with sub-200ms latency.

  • Asterisk PBX with PJSIP for high-density SIP trunk management
  • WebRTC gateway for browser-based agent softphones
  • Real-time call events via graphql-redis-subscriptions
  • CRM context injection with automatic screen pops on inbound calls
  • Intelligent routing with skill-based queues and VIP prioritization

Key Features

Unified Communication Features

Every feature is built for enterprise call centers — from SIP trunk management to real-time agent dashboards.

Asterisk IP PBX

Enterprise Asterisk deployments with high-availability clustering, automatic failover, and support for thousands of concurrent calls.

SIP Trunk Management

Multi-carrier SIP trunk provisioning with least-cost routing, quality-based failover, and real-time trunk health monitoring.

Real-Time WebRTC

Browser-based voice and video calling with WebRTC, enabling agents to handle calls from any device without softphone installations.

Unified CRM Dashboard

Real-time customer data dashboards with call context injection, screen pops, interaction history, and sentiment analysis.

Live Agent Analytics

Real-time queue statistics, agent performance metrics, call quality scoring, and SLA compliance tracking via GraphQL subscriptions.

IVR & Call Routing

Intelligent IVR trees with DTMF and speech recognition, skill-based routing, time-of-day rules, and VIP caller prioritization.
