The SPA3102 has serious echo problems with its PSTN port, but its FXS 
port and the SPA2102 don't seem to give people echo problems. FAX, on 
the other hand, can be a problem with the SPA2102 and SPA3102. Their 
T.38 implementation is quirky, and often fails when the lead from the 
ATA to the FAX machine is short (say 1m to 2m). A longer lead usually 
solves this. I have no idea of the cause.
