I may have 3 5550 consoles coming up for sale shortly. They are in great condition! Anyone know of a good outlet to get these sold for max value? I recently found a company to buy our stock of old 5330 phones with faded keys, cracked screens, etc. We are just now upgrading to MiVoice 7 and will be upgrading consoles to the new business console soon. I was hoping that Mitel would have some upgrade trade-in path. Has anyone had any success with that route?
