I've installed over 100 of these phones. I purchased them all here from VOIP supply. Out all these that I deployed I haven't had to replace one. They have been running for over a year now. I've had zero sound issues. I agree with the last reviewer abbreviations are very common on phones these days. If you want a feature rich solid phone with the Cisco name that is easy to deploy then look no further.
real world use
I sell these day in and day out, with 3cx. They are rock solid, easy to configure, and take a beating. if you can't understand xfer = Transfer, bxfer = Blind Transfer (no one needs to answer), and dnd = do no disturd, then you probally should not be looking at a VoIP system. Go find a Nortel or Avaya and use that instead.
Incredibly hard to use
Quality of the sound in receiver is awfull - always gives a feedback of my voice, so it sounds like I am talking to myself.
All its functions are hard to understand due to abbreviations. Even the simple call forward is like a mission impossible... You would not be able to figure it out by yourself without a manual...
