 number 2.  turn off Super G3 (33.6k) on fax machines.
  
 number 3.  turn off ECM (error correction Mode) on fax machines.
  
 This has almost fixed all my fax issues with ATAs.

 hello

i have faced a lot of problem while attaching the ATA with diffrent
 type of fax machines , problem with delayed tones , no tones , reception
  failure ...
i have noticed that it works with panasonic faxes without any problem ,
 but a lot of problem appears while connecting to canon ( i think it's
 super g3 ) , hp ,.....
any one know about the fax compatibility between ATA 186 and other
  machines ? , is it fax relay problem? .
the ATA is only an analog to digital conversion , & it treats that fax
 calls like g711 call without interpreting the fax tones only
 packetization is done , if we configure a dial peer pointing to the ATA connected
  to fax machines , can this solve the problem of the fax relay problem
 between different kind of faxes by configuring the dial-peer with fax
 relay parameters ,
