The receiver hung up when HylaFAX told them that the page was not received properly.

Again, the receiver hung up when HylaFAX told them that the page was not received properly.


HylaFAX can only do so much. If there is noise on the line or if the modulators on the modem generate noise, then HylaFAX cannot resolve that. Both of these logs indicate that some catastrophic noise event occurred to interfere with the data it received from the sender. HylaFAX informed the sender that the data was not acceptable, and the sender chose to hang up. What more can HylaFAX do?

You could check your lines for noise, and you could try a different brand and model modem (thus, switching the modulators) to see if a different one handles the problem a bit better.
