For Telstra
I had a Standard Telephone service connected on the 21st January 2000. The service had 8v+ on the exchange side of the pair, causeing the exchange equipment to drop the line when the line voltage dropped ( to protect Telstra's equipment). So the fact that I could make a call is irrelevent, if the call only lasted a few seconds, which ment that I had to call again, again and again. This was not what I would call a faultless service. even when calling telstra the line would dropout in the middle of the fault call. Local calls are not timed so should have been able to talk as long as I liked, and not have to make repeditive local calls. As for Telstra saying that this is satisfactory, is quite absurd!
I have proof of the fault that was reported to Telstra on the 18th of February 2000. I explained to the faults operator that I was a telecomunications technician & linesman and knew what I was talking about, and that a linesman had to physically go out and check the line, as this was the only way to determine were the fault was.

Note the creation time & date on the Telstra document! date:-2000-02-18 time:-16:03:34

The service was finally repair on the 23rd of august 2000, when a lineman went to the pillar and physically isolated the exchange side of the pair and found +8 volts foriegn battery on the exchange side. This is detected by the exchange equipement and the pair is isolated(disconnected).
