Transmission error with analog modems (Error Code:KB #9462)
Transmission errors with analog modems are often caused by a bug in the modem software (firmware) or by a DSP (Digital Signal Processor) with poor signal processing. We recommend to only use quality modems for fax operation, since low-cost modems usually do not work very reliable in practice. A list with recommended modems to be used with ActFax can also be found at Knowledge Base Article #9463.
Problems with bugs in the modem firmware can usually be solved by running the modem in fax class 1 mode with the following settings. By running a modem in fax class 1 mode, the modem software is only doing basic operations and most parts of the fax transmission are controlled directly by ActFax in that case. We also recommend to use at least ActFax Version 3.85, Build 0192 when running a modem in fax class 1 mode. .
