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
