Do I Need Microfilters In Every Socket?

[Nathaniel]

Hi Guys,

Im just in the process of setting up a new Broadband connection with o2, in my apartment i have 4 BT Telephone sockets however i only have 1 connected with any equipment and this is just a standard cordless home phone the other 3 sockets are empty without anything connected, will i need to place microfilters in all sockets including the 3 unused sockets? or just the 1 of which i will be running the telephone and wireless box?

Many Thanks
