How to test phone line for noise without phone
Hi, Im having internet connectivity issues, until recently my connection has become unreliable, its keeps disconnecting. When i try to detect the problem it says 'DNS server not responding'. I phoned my ISP and they said its not the DNS server, and to check for noise on the line. I dont have a phone/receiver for making voice calls so how can i test the line without a phone ?
I dont want to buy a phone just for the sake of testing for line noise, the phone no use to me, as i use a moble for all my outgoing and incoming calls only internet ADSL router is connected to the line; there are no other devices connected to the line and its in close range.
Im using windows 7, 64-bit and everything was fine before 5 days ago.
since i got no other devices connected on this line and there are no other electrical interferance does it mean someone is listening in or eavesdropping (even though i dont have a phone) ?
or is there a way i can listen to the line through my multimedia speakers on the computer table ?
thanx
