I did try fxotune.. it did wonders on echo and audio quality when
dialing in.
Before the zapata upgrade it did nothing (the -d -b options weren't there).
I found a page on voip-info.org that talked about using the new version and
followed what was there:
amportal stop
./fxotune -d -b 2
./fxotune -d -b 3
./fxotune -d -b 2 -w 1004
./fxotune -d -b 3 -w 1004
./fxotune -i 5 -t 1
./fxotune -d -b 2 -w 1004
./fxotune -d -b 3 -w 1004
./fxotune -i 4
./fxotune -s
amportal start
/etc/fxotune.conf:
2=5,3,251,250,2,253,255,255,254
3=5,1,248,252,4,253,1,0,0
If I run just plain old fxotune -i 4 then I get this in fxotune.conf:
2=14,0,0,0,0,0,0,0,0
3=5,0,0,0,0,0,0,0,0

Also although the 400P card says it's a revision J card it is detected
as a revision I card:
