You should get a lot faster.
Based on your current setup it's already maxed out though.
Chances are you are doing atleast one of the following:
Not in the master socket
Have poor internal phone wiring - how many phone sockets are in your house?
Using a long extension lead from the phone socket?
Not having every device filtered
Having a hardwired alarm that's unfiltered therefore?
Having a second master socket somewhere
Having an unfiltered sky box
Filtering after a phone splitter
Having star wiring - where there is no master socket
Do any of these apply?
