dujinfang,
hv u tried OSLEC? it's really reduced echo even on the cheapy X100P
card on *. oslec works w/ FS, too.
Thanks, will try. :)

I'm using openzap analog with tone_detect, it works(conference not

need tone_detect then.
Dujinfang,
Your telco must support "kewlstart" signaling for this to be
effective. The telco probably calls it something different, like
"disconnect supervision" or "drop in loop current" or "battery
reversal" or something like that. In any case, if the signaling is
supported then you need to set up your zaptel.conf with the
appropriate signaling type, which is either fxoks or fxsks. (I can
never remember because zaptel does it backwards where if you have
an FXO port then it uses FXS signaling but if you have an FXS port
it uses FXO signaling. Stupidity, to be sure, so be aware of it.)
1) Don't know why but the similar zaptel.conf works on asterisk. I
guess tone_detect in FS is equivalent to busydetect=yes in
Asterisk(zapata.conf) .
zaptel.conf
# Span 1: WCTDM/0 "Wildcard TDM400P REV I Board 1" (MASTER)
fxsks=1
fxsks=2
fxsks=3
fxsks=4
# Span 2: WCTDM/1 "Wildcard TDM400P REV I Board 2"
fxoks=5
fxoks=6
fxoks=7
fxoks=8
# Global data
loadzone = us
defaultzone = us
zapata.conf
usecallerid=yes
hidecallerid=no
callwaiting=yes
usecallingpres=yes
callwaitingcallerid=yes
threewaycalling=yes
transfer=yes
cancallforward=yes
callreturn=yes
echocancel=yes
echocancelwhenbridged=no
;echotraining=800
rxgain=0.0
txgain=0.0
group=0
callgroup=1
pickupgroup=1
immediate=no
busydetect=yes
I agree the FXO and FXS signaling is weird, why not they just match
the care name and reverse that internally?
2) Another essue is if I dial out from a FXO port from a local
extension(sip and zap), I can hear much echo on FreeSWITCH but not
much echo on asterisk. the zt.conf as below and I tried to change
the echo_cancel_level to 32 or 128 got no much difference. Is there
any equivalent configuration in FS like echocanccelwhenbridged=no in
asterisk? can I set busydetect and echocancelwhenbridged and other
options like this <param name="enable-analog-option" value="call-
swap"/> ?
[defaults]
codec_ms => 20
wink_ms => 150
flash_ms => 750
echo_cancel_level => 64
Find the sample zaptel.conf that comes with the zaptel package and
search it for fxsks or fxoks and you'll see some notes on how to
set it up for your analog trunks.
