Well, i did read it. And as per soundcard - have you tried to run ztmonitor 
without it? When i tried i just got:

arnor:~# /usr/src/zaptel-1.2.0-beta1/ztmonitor 1
Unable to open /dev/dsp: No such file or directory
Cannot open audio ...

so i guess it needs a soundcard after all...
Anyway, i installed a soundcard and run the ztmonitor. I went with the 
rxgain/txgain down to -6.0 ... the echo is not that loud anymore, but still 
is quite annoying. i'm at loss... no other bright ideas ...
