Still modern with the option to use older hardware **Rating:** 4.0/5.0 stars **Reviewed by:** Josh M. | Director, Computer & Network Security, Enterprise (> 1000 emp.) **Reviewed Date:** August 02, 2025 **What do you like best about MiVoice Office 400?** Mitel have been around a long time and this was a welcomed upgrade from 250, bringing with it the option for a hybrid environment offering both resiliency and an improved quality of service. **What do you dislike about MiVoice Office 400?** The configuration of a Mitel system can always be a little tricky but Mitel are always on hand to assist either on or off site and once you get the hang of the diagnostics and programming software it’s easy to get your head around. **What problems is MiVoice Office 400 solving and how is that benefiting you?** Hybrid working came with complications but we were able to utilise soft phones as well as a fully fledged desk phone solution. Teams integration is next on the list ### 2. From design implementation day to day management **Rating:** 4.0/5.0 stars **Reviewed by:** Surjeet K. | Senior Manager, Mid-Market (51-1000 emp.) **Reviewed Date:** May 11, 2024 **What do you like best about MiVoice Office 400?** I'm extremely please with our Mitel system, as are our end-user! From design, to implementation to day-to-day management, it's been seamless. The Mitel team has been professional, understanding and accommodating, always willing to listen to our suggestions or concerns and adjust accorindly. I've worked with many phones systems over the years, Mitel hands down has been the best! **What do you dislike about MiVoice Office 400?** In a busy work place a reliable phone system is a huge need. Sad to say, this system is the apocalypse of phones. Calls are dropped, people get stuck in a perpetual abyss and picking them up in the first place requires more work than technology should allow. Simple, reliable and dependable is not this system. Work orders put in fail to make it better **What problems is MiVoice Office 400 solving and how is that benefiting you?** Switched to Mitel when we cut the cord with Verizon. Excellent call clarity, more features, and about 1/3 the price of our old landline service. But the absolute icing on the cake is the customer service. Our old provider threw lots of obstacles in the way of porting our number, system upsells, and the Mitel team was superb in dealing with the issue. Calls answered immediately by live people who knew what they were doing and were pleasant to deal with, and emails answered within couple of hours instead of days ### 3.
