If you connect any expensive recording device to a telephone line without complete DC isolaation you risk burning out componnets on the device, not really woth wrecking a PC or its soundchip just to save on a cheap audio isolation transformer. Nowadays PSTN lines are often fitted with incorrect polarity too... without isolation you will lilkely get a nasty hum if you are fortunate or silence of a fried motherboard if you are not so fortunate. |

wihout a line isolation with transformer its a bad idea to plug your mic to phone. |
