Even in this configuration, with my impedance settings set to the Australian standard of 220+820||120nf, and the PSTN and PAP2 echo cancellers enabled (or not, and all combinations of) I get local echo as soon as I pick up the handset (I hear my voice bounced back to me). Surely this shouldn't be??? There is no hybrid involved at all!
'course there is. The telephone interface on the one end and the line interface on the other are both 2 wire. Did you have a phone line connected to the "other side". Running into an unconnected FXO port is likely to make echo because of the unbalanced impedance.
