Got wife to listen for noise (her hearing is superior to mine) and she heard no noise. I've yet to use a corded though. Today the up margin has been jumping around like a kangaroo on heat, that sat on a hornets nest. There is quite a problem with DSL connection

So I'm a bit stuck, as no noise no PSTN call reason.
I doubt it is at all relevant, but I have a MasterPlug tower. It has an input from the phone socket, and output to the router, so I ask if there is a downside to that configuration, that could be in part a culprit.
BTW just noticed the IPcanged @20:25, 20:36 and 20:44. Bit often isn't it?
