<div></div></div></blockquote><div><br>Dujinfang,<br><br>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.)<br>
<br></div></div></blockquote><div><br></div></div><div>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) . </div><div>

<div><br></div><div>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"/> ?</div>
