Mitel was established in 1973, making it one of the oldest providers of business communications and collaboration services. In terms of Mitel services in our Mitel Hosted PBX review was little we could fully compare as Mitel website is not designed to provide full information but rather attract (potential) customer contacts. Nonetheless, we were able to look at Mitel Hosted PBX, which based on the on the type of self-categorization a business may find a different set of features available. It's rather confusing as Mitel does have one plan for Small Business and another called Business Lite, in where business lite only differs in that it does not include any call.
With that said you'll find some of the usual Hosted PBX features, such as call park, call forwarding, and Hunt Groups. Most of the plans do include Unlimited Canada and US calling. Also, there is a nice feature called Unified Communicator Express PC Client; which allows communications using laptop/computers.
In all, we cannot fully assess the offering of Mitel Hosted PBX, but we do see some interesting features with a rather odd combination of plans. Given the experience, Mitel brings in the market the offers could be a perfect solution though in the market there are more clear alternatives to be considered.
