Since we moved into our new apartment we have had a kind of crackling, static type noise on the line that seems to come and go. We have DSL on the line and so I have replaced all of the filters in the apartment in case it was one of these, as well as disconnected all equiptment connected to the line and tried them one at a time. Still the noise is present.
The building is brand new and all the phone wiring runs over Cat5e cable, so there really shouldn't be any issues with the internal wiring I would hope.
Does anybody have any item what causes this kind of noise, and if it is likley to be a Telecom issue or an internal wiring issue. I dont want to call Telecom out and then have to pay them to fix something internal (As this should be done by the property developer if the wiring is shotty).
There are currently 5 devices on the line, 2x cordless phones, 1x DSL modem (unfiltered of course), 1x Fax Multifunction and the Sky decoder. Everything is filtered other than the DSL modem. We also seem to loose our DSL sync alot, moreso when on a phone call but sometimes just randomly. Phone calls are never cut off but both parties can hear the noise, which seems to come and go as it pleases.
I have recorded a sound byte of the noise by calling my VFX line from the Telecom line and leaving a voicemail message with the Telecom line handset on mute. Its here. (124KB wav file)
Also, here are my DSL stats, which are apparently good as we are close to the exchange.
