Slowness due to your phone?
On most of our IP phones there are two cables going into the phone. One of these cables goes to the socket in the wall, and the other cable connects the computer(s) in the room to the phone. If the computer seems very slow or unresponsive, or the network seems very sluggish (such as web pages loading very slowly), you can try to disconnect both cables from the phone, wait five to ten seconds, and then reconnect the cables again. Please ensure the cables go back in the same positions they were before they were disconnected.
During this process your computer might "hang" and refuse input, but just give it some time. It will take the computer a little while after the phone becomes active again before you can restart your work, but once the phone is back you should be able to continue as normal. If your system is still very slow after this process, please don't hesitate to contact us for further assistance and remember to include the name of your computer and your office number in the email you send us.
