Outcome
Enterprise voice moved to Teams with PSTN continuity and the legacy platform retired.
The problem
Enterprise voice still ran on a legacy Skype for Business platform across multiple data centres, while collaboration had already moved to Teams.
What I did
- Led the full migration of users, numbers and call flows to Teams Phone.
- Designed PSTN integration and collaborative calling for the new platform.
- Automated bulk changes with PowerShell to keep cutovers fast and repeatable.
- Migrated the remaining voice infrastructure to virtualised hardware and documented the environment end-to-end.
Result
One platform for meetings, chat and calling, with a supportable, documented voice environment.
