Case Study: Centralized IP Phone Directory App for Secure Police Communication

Client: Bangladesh Police – Police Headquarters (PHQ)
Delivered by: Opus Technology Limited
Client Website: https://www.police.gov.bd

Client Overview

The Police Headquarters (PHQ) of Bangladesh Police oversees thousands of officers and administrative personnel across multiple units, divisions, and operational wings. Fast, reliable, and secure internal communication is essential for day-to-day coordination, command dissemination, and emergency response.

Previously, PHQ relied on paper-based directories and manually maintained contact lists, which often contained outdated information. This created delays in reaching key personnel and hindered operational efficiency. To solve these challenges, PHQ required a centralized, secure, and easily accessible digital phonebook integrated with their existing IP telephony infrastructure.

Project Summary

Opus Technology Limited developed and deployed a customized IP Phone Directory App designed specifically for the internal communication needs of Bangladesh Police. The solution provides a centralized, always-updated directory optimized for secure access, fast search, and direct dialing.

Accessible from both desktop and mobile devices, the app enables authorized personnel to quickly locate verified contact information and initiate calls instantly using the integrated IP phone system.

Key Objectives

• Centralize internal phone directory data across all PHQ departments
• Enable quick search and seamless direct dialing from within the application
• Maintain real-time, accurate contact information with controlled admin access
• Improve coordination and response time during routine operations and emergencies
• Provide secure, role-based authentication and access controls

Challenges

• 🚫 Paper-based phonebooks became outdated quickly and were difficult to maintain
