• Establish and document the target-state architecture for the Network Services domain, encompassing SIP trunk consolidation, SBC configuration templates, and dial-plan normalization.

• Detect and resolve enterprise DNS conflicts and IPAM-related challenges across various legacy network environments.

• Create standardized configuration templates and architectural guidelines for Voice and SIP services to facilitate extensive automated deployments.

• Design routing frameworks for emergency and authenticated communications, ensuring alignment with regulatory and compliance mandates while collaborating with client legal teams for necessary approvals (e.g., e911, STIR/SHAKEN).
