use error correction mode
Error Correction Mode (ECM) eliminates data lost due to poor phone lines by
detecting errors that occur during transmission and automatically requesting
retransmission of the erroneous portion. Phone charges are unaffected, or might
even be reduced, on good phone lines. On poor phone lines, ECM increases
sending time and phone charges, but sends the data much more reliably. Turn
ECM off (the default setting is on) only if it increases phone charges
substantially, and you can accept poorer quality in exchange for reduced
charges.
