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.
- 1. 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.
- 1. Network Configuration & Optimization

- Configure SIP protocols, routing, and call flows.
- Optimize IMS network performance and ensure KPI adherence.
- Support parameter tuning and capacity management.
- 1. 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.
- 1. Collaboration & Stakeholder Management

- Work closely with solution architects, design teams, and customers.
- Coordinate with cross-functional teams (Cloud, PACO, Transport).




- Support customer discussions and technical workshops.
- 1. Documentation & Reporting

- Prepare integration plans, test reports, and acceptance documents.
- Maintain knowledge repositories and standard operating procedures.
