[Freeswitch-users] session:recordFile(-) always creates empty wav file during outbound IVR call

I tried it again in the following three cases of outbound ivr calls according to you and anthony's advice, I get the same result (i.e. record empty wav file with its size 68 bytes), nothing seems to be improved.
For inbound ivr call, application 'record' never has a problem!
 
originate {record_waste_resources=true, ignore_early_media=true}sofia/gateway/mygateway/1726011  8884
 
originate {record_waste_resources=true}sofia/gateway/mygateway/1726011  8884

originate {ignore_early_media=true}sofia/gateway/mygateway/1726011  8884
 
-- Here is the xml dialplan for extension 8884:
 
 <extension name="Play and Record Sound File">
  <condition field="destination_number" expression="^(8884)$">
   <action application="answer"/>
   <action application="sleep" data="1000"/>
   <action application="playback" data="ivr/ivr-thank_you.wav"/> 
   
   <action application="record" data="C:/c4dev/freeswitch/Debug/sounds/test.wav 20 200"/>
   
   <action application="sleep" data="1000"/>
   <action application="playback" data="voicemail/vm-goodbye.wav"/> 
   
   <action application="sleep" data="1000"/>  
   <action application="hangup"/>   
  </condition>
 </extension>

Tony mentioned something that might be an issue for you. Try setting this on the channel:
http://wiki.freeswitch.org/wiki/Channel_Variables#record_waste_resources


Let us know if that makes a difference.

Hi Anthony,

Actually FreeSwitch application "record" doesn't work either for outbound IVR call (see below), created an empty wav file with its size 68 bytes, the wav file doesn't contain any samples of audio data;

<action application="record" data="C:/c4dev/freeswitch/Debug/sounds/test.wav 20 200"/>

earlier I reported that "session:recordFile(-)" doesn't work inside Lua Script for any outbound IVR call.

- My CLI commands to make an outbound IVR call:

originate {ignore_early_media=true}sofia/gateway/mygateway/1726011  8884
or
originate user/1005   8884

- xml diaplan for extension 8884:
{
       <extension name="Play and Record Sound File">
               <condition field="destination_number" expression="^(8884)$">
                       <action application="answer"/>
                       <action application="sleep" data="1000"/>
                       <action application="playback" data="ivr/ivr-thank_you.wav"/>

                       <action application="record" data="C:/c4dev/freeswitch/Debug/sounds/test.wav 20 200"/>

                       <action application="sleep" data="1000"/>
                       <action application="playback" data="voicemail/vm-goodbye.wav"/>

                       <action application="sleep" data="1000"/>
                       <action application="hangup"/>
               </condition>
       </extension>

}
