The Mitel SMB Controller 8/38G (50008381) is a dedicated MiVoice Business controller designed for small and medium businesses or branch offices that need a powerful, all-in-one IP phone system and unified communications platform. Supporting up to 150 users, this compact rack-mount appliance delivers reliable call control, voicemail, auto-attendant, and advanced UC features in a cost-effective, on-premises solution. With 8 GB RAM and a 38 GB SSD, the SMB Controller provides the performance and capacity needed for growing VoIP deployments while helping organizations migrate from legacy Mitel platforms like MiVoice Office 250 and MiVoice Connect. This Mitel SMB Controller enables the full MiVoice Business feature set, including unified messaging, flexible call routing, hot desking, teleworker support, and integrated conferencing to keep distributed teams connected. It also supports collaboration applications such as MiCollab, MiTeam Meetings, Microsoft Teams integration, and Mitel Revolution, allowing businesses to add video meetings, messaging, and mass notification on the same common platform. Integrated MiVoice Border Gateway functionality (for SIP trunking and remote workers), CloudLink Gateway, and a built-in probe for Mitel Performance Analytics help simplify deployment, monitoring, and future expansion.
