I purchased this machine because it has the most recording time and most mailboxes of all the consumer systems out there--I need these features for my business.  I also need the recording quality to be good, like your run-of-the-mill commercial voicemail system (or the old cassette-type machines) because I need to capture and edit these voice messages on my computer.  On the recommendation of a couple of reviewers in this forum who stated that the voice quality was great, I decided to give this model a try.
