Did you try to get a milliWatt test phone number from your telco? It
was really easy for me. I called the business office and told them that
"my new digital pbx was having some awful echo trying to deal with their
lines; all I needed was a milliWatt test line to balance my receive and
transmit gains properly". I then had to tell her what a milliWatt test
line did and why I thought it would help me; she didn't know what it
was, but she was more than happy to have repair call me to see if they
could help me. Less than a half an hour later, somebody called up,
asked for me, and said "lets see.. milliWatt test line for Sitka...
747-1100" as easy as that. I spent a half an hour making calls to this
number out of my (phew, only three!) zap lines and haven't had echo
troubles since.
BTW, the area code on that one is 907 if you want to listen to what it
should sound like. If the telcos were to route amongst themselves fully
digitally, wouldn't you be able to use my mW test line no matter where
you are? As long as the only analog link between it and you was your
local copper pair? Just in case, I wouldn't recommend anybody tuning
themselves to this mW source.

No that just means you are not calling ztmonitor properly.
Try running ~# ztmonitor 1 -v

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 ...
