Switch from Mitel
Moving from Mitel to 3CX
Mitel and ShoreTel systems have served businesses well for years, but many are reaching end-of-life with costly upgrade paths. 3CX is a modern replacement that keeps the features your team relies on and adds mobile apps, Microsoft 365 integration, and flexible hosting.

Why businesses move
Common frustrations with Mitel
End-of-life platforms
Older Mitel and ShoreTel models are losing support, which forces an expensive upgrade or a move.
Complex licensing
Feature licenses, software assurance, and hardware renewals are hard to track and budget.
Limited flexibility
Adding sites or remote workers often means more hardware and more licensing conversations.
