Call Center Platform

The Challenge

The client provides outsourced contact center services to businesses across multiple industries. Their existing infrastructure relied on a patchwork of disconnected systems: a standalone SIP phone system for call routing, a separate CRM for client data, spreadsheet-based scheduling, and manual reporting. Supervisors had no real-time visibility into call queues, agent availability, or service levels. When a client called, agents had to Alt-Tab between three applications to find the relevant information -- adding seconds to every interaction and frustrating both agents and callers.

As the center grew, the inefficiencies compounded. Training new agents took weeks because the workflow spanned so many disconnected tools. Quality monitoring required managers to listen to recordings after the fact with no way to intervene during live calls. The company needed a unified platform that would bring telephony, CRM, and management together in a single interface.

The Solution

We built an integrated call center platform that unifies SIP telephony with CRM functionality and real-time management tools. The system uses Asterisk as the telephony engine, handling call routing, IVR menus, queue management, and recording. A Node.js middleware layer bridges the phone system with the React-based agent and supervisor interfaces via WebSocket for real-time state synchronization.

When a call arrives, the system identifies the caller, pulls their complete history from the CRM, and presents it to the agent alongside the active call -- all in a single browser window. Supervisors see a live dashboard of every queue, every agent's status, and every active call, with the ability to listen in, whisper-coach, or barge into calls as needed.

Key Features

• Unified agent desktop -- A single-screen interface that combines the active call controls (answer, hold, transfer, conference), the caller's CRM record, previous interaction history, and a scripting panel. Agents never leave the application.

• Intelligent call routing -- Inbound calls are routed based on configurable rules: skill-based routing, round-robin, longest-idle agent, or priority queuing for VIP clients. The IVR system handles initial caller classification before connecting to an agent.

• Real-time supervisor dashboard -- Live metrics including calls in queue, average wait time, agent statuses, active calls, and service level percentages. Supervisors can drag agents between queues, force-logout idle agents, and adjust routing priorities on the fly.

• Call recording and quality management -- All calls are recorded and indexed by agent, client, and campaign. Supervisors can search, replay, and score calls against quality rubrics. Flagged calls are automatically routed to QA reviewers.

• Campaign management -- Outbound calling campaigns can be created with uploaded lead lists, configurable dialing modes (preview, progressive), and per-campaign scripts. Agents see campaign-specific information and talking points automatically.

• Performance analytics -- Detailed reports on agent productivity (calls handled, average handle time, wrap-up time), campaign results (contact rates, conversion rates), and service levels (abandon rates, wait times). Reports can be scheduled for automatic delivery.

• CRM integration -- Complete contact management with custom fields, interaction history, tagging, and search. Client records update in real time during calls, so notes and dispositions are captured immediately.

Results

Call handling capacity increased by 40% without adding agents, thanks to the elimination of multi-application workflows and intelligent routing that reduced idle time. Average handle time dropped by 25% as agents had caller information instantly available rather than searching across systems.

New agent onboarding time fell from two weeks to two days. The unified interface and built-in scripting meant that new hires could start handling calls with minimal training, following guided workflows rather than memorizing procedures across multiple systems. For the client's management, the real-time supervisor dashboard was transformative -- shifting from reactive, after-the-fact management to proactive, real-time operational control.
