DO NOT RECOMMEND!
We signed up with Fonality about 4-5 months ago.  I have had issues to deal with everyday!  We were promised by Ricoh (the company that installed everything for us and were supposedly "experts") that the remote phones would work.  We were told that we would be able to unplug a phone and take it whereever we wanted and it would work as if they were "right here in our main office".  Having remote phone capability is the main reason we decided to go with VOIP and Fonality.  The remote phones never worked.  Then, Ricoh told us that we need to purchase a SonicWall to fix the remote phone issue.  We spent $1600 on this SonicWall, and our remote phones are still not working.  We recently had people move from one office into another (all within the same building) - now, their phones and HUD are not working.  There is a new issue everyday.  Literally.  Another extension was working, now isn't for no reason.  I'm actually on the hold with Fonality right now (for 41 minutes so far), while they attempt to correct the issue.
I will say that most...well...some of the reps are helpful.  It typically takes at least 1-5 hours out of my day to get all of these issues corrected, but I don't always hang up angry.  Sometimes they actually help.
Bottom line:  I would stay away from Ricoh (the supposed experts) and Fonality.  Both are way too pricey for the less than mediocre service and product that you receive!
