Sending a fax to this destination delivers only the coverpage, then the error +FPTS:2 (bad page, retrain requested) (retrain negative) occurs and the sendprocess is aborted.

I found one particular number that cannot receive a fax from hylafax (Hylafax Beta 18, Sunos 4.1.3, Zyxel U1496 , Firmware V6.16M). Sending a fax to this destination delivers only the coverpage, then the error +FPTS:2 (bad page, retrain requested) (retrain negative) occurs and the sendprocess is aborted. If the modem will retrain or not is as far as I know determined by the modem parameter *Q1 (*Q2, *Q3, *Q0) (this is for zyxel modems; other modems use eg %E1 %E0 for this purpose). Our modem was set to *Q2 which means to use the next slower transferspeed if the signal quality is bad and to speed up again, if the signalquality of the telephone line gets better again. Perhaps one sould try either *Q1 (initiates a real renegotiation if signalquality is bad) or *Q0 (no renegotiation at all). The AT*Q command relates to a data connection and not a fax connection (unless you know something that I do not). Retraining during a fax session is required when the receiver requests it through the post-page message response--in this case "RTN" or ReTrain Negative (acknowledgement of the received page data). Problems of this sort are typically caused by a poor phone connection but sometimes may be due to improperly encoded page data or, if ECM is being used, a bug in the ECM protocol. The session log that was supplied indicated ECM was not being used so the only reasonable possibilities would seem to be bad data or a bad phone connection. The former is highly unlikely and the original poster did not indicate if the problem was reproducible or if they'd tried a different phone line. Sam
