Mitel MiVoice Connect Voice Switches and Routers
Benefits of Voice Switches
Voice Switches for Every Need
Highly reliable and intelligent, Mitel switches unify communications across multiple enterprise locations, supporting IP phones, analog devices, and a variety of trunk interfaces. To provision additional locations, simply add a voice switch to handle the number of phones and any local trunking needed at the new location.
Compact Design
The ST Series Voice Switches are compact 1U rackmount units that provide the physical link between your local telephone service provider and the IP network.
Hassle-Free Management
Embedded Linux means there is no need to install or manage the voice switch operating system separately. Switch configuration and management is supported by the Windows Server OS-based “HQ” server.
