Everything You Need for Enterprise Call Management

Multi-Vendor CDR Collection

Connect to 14+ PBX systems across four major vendors. TCP Push, TCP Pull, and SFTP collection methods ensure compatibility with any deployment.

Real-Time Wallboards (Mitel CX)

Live supervisor dashboards streamed from Mitel CX via SignalR — not report-refresh polling. Queue Waiting Interactions widget, per-agent presence, TV kiosk mode, and Alert Center overlays across browser, phone, and TV.

Modern Web Interface

Built with Blazor WebAssembly for a fast, responsive experience. Access your data from any browser — no plugins or desktop client required.

Multi-Tenant Architecture

Manage multiple organizations, sites, and PBX systems from a single installation. Role-based access control ensures data isolation between tenants.

Detailed Reporting

Generate comprehensive call reports by extension, department, trunk, or cost center. Export to Excel and PDF. Schedule automated report delivery.

Cost Management

Track call costs with configurable tariff tables. Identify expensive calling patterns, allocate costs to departments, and optimize trunk utilization.

Call Center Reporting

Mitel CX ACD analytics built in — queue performance, agent productivity, digital channels, IVR workflows, and AI-powered insights. No separate application needed.

Emergency Alerts (SNMP)

Dedicated SNMP Trap Receiver decodes Mitel Emergency Response events (911 / 999) against the MITEL-ERN MIB, correlates against a CESID location map, and fans out to phones, desktop notifier, and email groups in under a second. Full acknowledgement fabric across all surfaces.

Phone Display (Mitel 6900)

Turn every Mitel 6900 handset into an EVOA surface. Push status screens, ACD Agent Status live presence, caller-tag surfacing with per-tag push flags, full-color ImageScreen for branded displays. Model-aware layouts for 6920, 6930, and 6940. Licensed per seat.

EVOA Desktop Notifier

Lightweight Windows tray app — signed, silent auto-update, no browser session required. Full-screen popups for emergency, VIP, tagged-caller, and alert-rule events. Per-category custom sounds, hardened SignalR reconnect, Certum EV signed for zero SmartScreen warnings.

Call Center Module

Mitel CX Call Center Reporting

Purpose-built ACD analytics for Mitel CX deployments. Track queue performance, agent productivity, digital channels, and IVR workflows — all within the same unified interface as your CDR reporting.

Queue Performance

Per-queue metrics: offered, answered, and abandoned calls; service level; average wait and handle times; overflow and interflow statistics.

Agent Analytics

Individual performance tracking: ACD calls, talk time, wrap-up, utilization %, make-busy, DND, and full login/logout audit trails.

Digital Channels

Mitel CX Digital reporting across all media types — digital queue performance, agent activity, and interaction detail for voice, chat, email, and more.

IVR Analytics

IVR workflow and condition performance, port utilization tracking, ANI/CLI analysis, and subroutine-level drill-down reports.

AI-Powered Insights

Intelligent call center summaries and anomaly detection powered by your choice of AI provider — Anthropic, OpenAI, Azure OpenAI, or on-premises Ollama.

Custom Report Builder

Design your own ACD reports with custom column selection across all data sources. Save configurations, schedule automated delivery, and export to Excel or PDF.

Architecture

Built for Scale and Reliability

Collection Service

A dedicated Windows Service handles all PBX connections. Runs independently of the web interface, ensuring CDR data is collected 24/7 even during maintenance windows.

  • Automatic reconnection on PBX failures
  • Buffered CDR processing for high-volume systems
  • Delayed-auto start + failure actions for power-loss recovery
SNMP Receiver Service

A separate Windows Service listens on UDP 162 for SNMP traps from Mitel Emergency Response, decodes them against the MITEL-ERN MIB, and hands events to the Web API for fan-out to phones, notifier, and email groups.

  • Local trap-source allow-list
  • CESID location correlation
  • Sub-second event dispatch to all recipient channels
Web Application + SignalR

Blazor WebAssembly frontend with ASP.NET Core Web API on .NET 10. Hosted on IIS with the /api + /ui split. Embedded SignalR client streams events from Mitel CX; SignalR hub pushes to browser, phone, TV, and desktop notifier surfaces.

  • RESTful API + SignalR real-time hub
  • PostgreSQL 17 (master + per-tenant databases)
  • Role-based access with tenant-scoped permissions
Collection Methods

Three Ways to Collect CDR Data

Choose the method that works best for your PBX deployment.

TCP Push

The PBX pushes CDR records to the Collection Service over TCP. Real-time delivery with minimal configuration. Supported by most PBX systems.

TCP Pull

The Collection Service connects to the PBX and retrieves CDR records on demand. Ideal for systems behind firewalls or with restricted outbound access.

SFTP

Collect CDR files from an SFTP server or local folder. Automatic polling with configurable intervals. Perfect for Cisco CUCM and batch-oriented systems.
