Migrate From Skype for Business to Modern VoIP, With Zero Data Loss
Skype for Business has reached end of life, consumer Skype was retired in May 2025, and Skype for Business Server 2015/2019 lost official support in October 2025. Businesses still running these systems face rising security risk and shrinking vendor support. Unified Voice manages the full transition to a modern VoIP platform with structured migration support, so you keep your call logs, contacts, and user permissions intact.
Skype for Business Server 2015 and 2019 no longer receive security patches, which leaves unmigrated systems exposed to unpatched vulnerabilities. Third-party integrations built for Skype for Business are also degrading as vendors shift their focus to modern platforms like Teams and dedicated VoIP systems. The longer a migration is delayed, the more complex and costly it typically becomes.
