Midsize Business Communications Solutions

Midsize companies typically solve enterprise problems with lean IT teams. Multiple sites, a growing contact center, hybrid staff, compliance obligations, with a slim headcount to run it all. Mitel connects your locations, employees, and customers with a communications landscape, deployed where you want it: on-site, in a private cloud, in the public cloud, or a mix you adjust over time. Run it yourself, hand day-to-day management to Mitel or a certified partner, or split the work between you.

Why Midsize Organizations Choose Mitel

Midsize is where one-size-fits-all breaks down: pure-cloud suites assume you'll rebuild around them, and legacy PBX vendors assume you'll stand still. 

Mitel builds for the organizations in between. You choose the deployment model per site, migrate at your own pace, and add contact center, collaboration, and vertical integrations on the platform you already run. 

Mitel is a top provider in unified communications globally, with 70M +users across 100+ countries, and midsize organizations of 500 to 5,000 employees are the center of that install base, from regional health systems to local governments and councils to multi-campus schools.

" The Mitel solution makes people working from home intuitive. Our single greatest change has been the ability to work from anywhere. This has been huge for us. "
Becky Farmer , CEO Center for Sports Medicine and Orthopaedics
" Instead of building a front end ourselves, we were able to bring in Mitel’s solution and very quickly set up a Google chatbot. "
John Kelly , Head of Data Intelligence North Yorkshire County Council
" We really appreciated Mitel’s experience with local governments. It was important to me to know that peers I respect – people who have been in the business longer than me – have chosen Mitel. "
Frank Birkenhauer , Assistant Township Administrator, Colerain Township (OH, USA)
