Buzzing noise on line goes when dialling and making a phone

Have a filtered faceplate at the master socket, so should i remove this and plug phone into the test socket, the BB seems fine but could the filtered faceplate be on its way out ( 7 years old ) and BB is interfering with the phone.
The thing is though like i said the noise goes when making or receiving a call. Sky adsl BB and line.

Yes, plug a corded phone into the master socket test socket, and test.

Ok thanks.

I will plug straight into test socket without a filter. If there is still noise does that imply a outside line fault, and that it does not fall on me to sort out? but upon the line provider.

Yes, assuming the phone itself is not faulty of course.

Plugged 3 phones direct into test socket no filters, still buzzing on the line but not affecting the actual phone calls or BB, only hear it before i dial and not during a phone call, very strange!
Not much chance all 3 phones are the problem, so i take it its the outside line etc that is causing the buzzing

It is a fairly loud buzzing and not a crackling.

The only danger is if they consider a buzzing present only during the dial tone not to be service affecting, and then bill you for the call out.

Isn't this called dial tone?

You hear the buzzing over the dial tone?

I was assuming the buzzing noise is over the top of the dial tone, maybe the OP can clarify.

As soon as i press the first number to dial all the buzzing goes away, never had loud buzzing before dialling in the past, never.

Just checked the router stats and being on a long line 56db atten we have been connected at 3.7mbps down and 620 up.
Now connected at 4.4mbps down and 1066 up, sky have something which checks the line dont they? and resets it.
Any chance the buzzing is caused by setting the BB to high and interfering with the line,but is perfectly ok to leave as it is?
