Use Cases and Deployment Scope
I've used MiVoice Business as my last 3 companies all of which were upgraded from the Shoretel system. Moving to the Shoretel platform allowed us to get rid of a very old and expensive PBX system that was growing increasingly difficult to maintain. Shoretel was a large and expensive transition, the maintenance costs are much better. The MiVoice upgrade allowed a slightly better use experience/client. With Virtual appliances that MiVoice Business introduced, it was relatively easy to save even more with getting rid of older incoming PRI trunks and move to SIP trunks. We saved money and got better resiliancy.
