Microsoft Teams Integration
Mitel offers two paths to Microsoft Teams integration. The Direct Routing path (on premises or hybrid) connects existing Mitel MiVoice PBX platforms to Teams via a certified SBC, preserving your telephony investment while giving every Teams user full PSTN calling with bi-directional presence sync. The Unify Phone path (cloud) is a cloud native telephony service embedding enterprise grade voice calling directly inside Teams, providing PSTN calls, hunt groups, voicemail, and call recording without any on premises infrastructure, backed by a 99.99% uptime SLA.
