• Build a report document that includes:
• - Executive summary and transformation benefits

• - Migration stages with associated risks, commercial impact, and architecture evolution
• - Integration with call recording, compliance tools, and legacy services

• Deep knowledge of Avaya systems (Aura, IP Office, CM, etc.) and telephony infrastructure (SBCs, SIP trunks, gateways).
• Expertise across Microsoft Teams Voice ecosystem: Operator Connect, Direct Routing, Microsoft Calling Plans, Teams Phone System.
• Familiarity with regulatory requirements and integrations (e.g., PCI-DSS, MiFID II, call recording, CRM, etc.)
• Experience in producing customer-facing consulting artefacts with a high standard of technical depth and executive relevance.
• Excellent stakeholder engagement and communication skills.
• Microsoft 365 Certified: Teams Voice Engineer Expert (MS-720 or equivalent)
• Avaya certifications (ACSS, ACIS) or similar vendor credentials
• Experience with compliance voice recording platforms (e.g., NICE, Verint, ASC, RedBox)
