Are your pc`s plugged into the back of the phones ? Is this for all users or just one etc.. ? If the pc is plugged into the back of the phone what happens if you unplug and leave the phone standalone? What switches are you using....

Sorry for all the questions...

The pc's are plugged into back of phone and it is affecting the majority of people on site. Not sure of switch type.

As stated above have you unplugged the pc`s from the phones? Also are your pc`s and phones on two different vlans ?
