Static on line

[Misadventure]

Hi All,

Since upgrading to a S8700 solution we have static noise in the background of all calls - some extensions are worse than others...

Also some lines appear faint...

Extensions are not on the same card and also in different cabinets - any ideas anyone?

I had a simlar problem but on a DCS tie between two buildings. CHeck the physical connections and make sure they have a solid connection or even reseat them
