Simplifying Complex Telecom Integrations Using a Scalable Numbering Platform

Built to handle high availability, massive scale, and complex telecom integrations.

Client

A US-based telecom software provider serving 15+ telecom operators across 10+ countries, delivering large-scale numbering and regulatory solutions for telecom networks worldwide.

The Challenge

The client operated a complex, multi-node telecom numbering platform processing millions of transactions per day. The platform required modernization without compromising reliability or regulatory compliance. As the platform scaled, several challenges emerged: 

  • Ensuring high availability and horizontal scalability for mission-critical workloads
  • Managing deep integrations with enterprise systems, network elements, and regulatory platforms
  • Supporting hundreds of concurrent users without performance degradation
  • Maintaining a legacy UI framework nearing end-of-life with limited browser compatibility imited Accessibility: No intuitive interface for asking plain-language questions; only tech-savvy users could dig deep.
  • Reducing operational risk while continuing uninterrupted telecom operations

Our Strategy

TechTez adopted a platform-first modernization strategy, focused on resilience, integration clarity, and long-term scalability. 

  • Designed a highly available, horizontally scalable architecture capable of handling sustained high transaction volumes 
  • Established a clear integration orchestration layer to manage enterprise, network, and regulatory interactions 
  • Modernized the UI using Angular and REST-based services to support parallel users and modern browsers 
  • Reduced dependency on proprietary frameworks by adopting open-source, enterprise-proven technologies 
  • Ensured modernization was delivered without disrupting live telecom environments 

Architecture & Workflow

Platform Highlights:

  • Built to process millions of transactions per day
  • Active-active architecture supporting high availability
  • Seamless integration with Enterprise EAI systems, Telecom network elements and Central regulatory databases
  • Scalable UI supporting hundreds of concurrent users
  • Secure, standards-based communication across all integrations

Technology Architecture

  • Application & Runtime: Java 8, JBoss 7, Apache Web Server  and Red Hat Enterprise Linux 
  • Integration & Services: JMS, IBM MQ, TIBCO, RESTful & SOAP Web Services, CORBA, TCP/IP 
  • Data Layer: Oracle, MySQL 
  • User Interface: Angular, Struts 
  • Quality, Performance & Delivery: Silk Performer, JMeter, Selenium, Robo Framework, SOAP UI and JIRA 

Why It Matters

Telecom numbering systems are foundational to network operations downtime or failure is not an option. By modernizing the platform while preserving operational continuity, TechTez helped the client:

  • Safely scale mission-critical telecom services
  • Simplify complex integrations across the telecom ecosystem
  • Extend the lifespan of a core platform without disruptive rewrites 

Results

  • Improved platform stability and fault tolerance
  • Enabled horizontal scalability to meet growing transaction volumes
  • Reduced long-term maintenance and customization effort
  • Enhanced user experience with a modern, scalable UI
  • Strengthened regulatory compliance and integration reliability
  • Positioned the platform for future cloud-native evolution
