(Nextiva is my VOIP provider) because my Polycom VVX201 stopped working four months after I purchased it (also on the recommendation of Nextiva) after the office rebooted the server and the VVX started sending me ghost calls every five minutes

I bought the "Genuine polycom 48 volt power supply for polycom ip phones 2200-46170-001" for power and it works perfectly

Great Polycom Quality
