This was actually very well known back in the days Before The Internet [I.E. BBS days}. The original series of Telstra's "Touchphone 200" recharged its internal memory battery from the phone line by - you guessed it - pulling a certain voltage from the line at an interval of every 20 minutes - regardless of the fact that the line was in use or not. This wasn't generally a problem for voice calls - but for data calls, it meant disconnection every time. The solution was to unplug the T200 while making a data call. Later versions have {the ones with the raised buttons as opposed to the flat membrane type buttons}, supposedly, had the problem corrected.
