Roles & Responsibility
Role Overview
The Solution Integrator – IMS is responsible for end-to-end integration, configuration, testing, and deployment of IMS solutions within telecom networks. The role ensures seamless interoperability of IMS components across multi-vendor environments while maintaining high service quality and reliability.
Key Responsibilities
1. Solution Integration & Deployment
Perform end-to-end integration of IMS nodes (e.g., CSCF, SBC, TAS, DNS/ENUM).
Execute installation, configuration, and commissioning of IMS solutions.
Preparation of delivery specific MOPs and execution of Live node Activities.
Ensure alignment with design documents, HLD/LLD, and customer requirements.
2. Testing & Validation
Conduct system integration testing (SIT), interoperability testing (IOT), and user acceptance testing (UAT).
Validate VoLTE, VoWiFi, and other IMS-based services.
Troubleshoot integration issues and ensure defect resolution.
3. Network Configuration & Optimization
Configure SIP protocols, routing, and call flows.
Optimize IMS network performance and ensure KPI adherence.
Support parameter tuning and capacity management.
4. Troubleshooting & Support
Analyse logs, traces, and signalling flows (SIP/DIAMETER).
Identify root causes and implement corrective actions.
Provide L2/L3 support during deployment and post-integration phases.
5. Collaboration & Stakeholder Management
Work closely with solution architects, design teams, and customers.
Coordinate with cross-functional teams (Cloud, PACO, Transport).
