“I have been working with Mitel (& PCS) for almost two years now. I did not have any training when I began using the system at a new job. The system is quite easy to learn and has so many great options such as voicemail to your email. Even if you accidently delete the message from your phone you can replay it through your computer. I love the instant messaging. You can be on the phone with a client and message a co-worker with a question at the same time. I believe this system saves me precious time on a daily basis. I have worked with several phone systems in my time but this one has to be by far the greatest. ” -M.E. Dey associate.
