   首先备份/usr/local/freeswitch/conf/dialplan/default.xml 。

然后vi编辑default.xml ，在

<extension name="Local_Extension">
     <condition field="destination_number" expression="^(10[01][0-8])$">
下面加入以下语句即可录音。

<action application="set" data="RECORD_TITLE=Recording ${destination_number} ${caller_id_number} ${strftime(%Y-%m-%d %H:%M)}"/>
   <action application="set" data="RECORD_COPYRIGHT=(c) 2011"/>
   <action application="set" data="RECORD_SOFTWARE=FreeSWITCH"/>
   <action application="set" data="RECORD_ARTIST=FreeSWITCH"/>
   <action application="set" data="RECORD_COMMENT=FreeSWITCH"/>
   <action application="set" data="RECORD_DATE=${strftime(%Y-%m-%d %H:%M)}"/>
   <action application="set" data="RECORD_STEREO=true"/>
   <action application="record_session" data="$${base_dir}/recordings/archive/${strftime(%Y-%m-%d-%H-%M-%S)}_${destination_number}_${caller_id_number}.wav"/>

大家应该看明白了，录音会自动存放在${base_dir}/recordings/archive下。
