Recording a call in FreeSWITCH

The FreeSWITCH wiki page explains the call recording in details, and I’m using the following extension in my dialplan. Whenever I prefix the destination number with “#”, the outgoing call is automatically recorded. It’s also easy to add an execution of a Lua (or Javascript)  script which would insert the file name into some sort of a database, and then a front-end application would be able to retrieve the file (I’m just using FileZilla for myself).

    <extension name="start_recorder">
      <condition field="destination_number" expression="^\#(\d+)$">
        <action application="set" data="RECORD_TITLE=Recording ${destination_number} ${caller_id_number} ${strftime(%Y-%m-%d %H:%M)}"/>
        <action application="set" data="RECORD_ARTIST=DVOP.net"/>
        <action application="set" data="RECORD_DATE=${strftime(%Y-%m-%d %H:%M)}"/>
        <action application="set" data="RECORD_STEREO=true"/>
        <action application="set" data="media_bug_answer_req=true"/>
        <action application="record_session" data="$${base_dir}/recordings/${strftime(%Y-%m-%d-%H-%M-%S)}_$1_${caller_id_number}.mp3"/>
        <action application="transfer" data="$1 XML default"/>
      </condition>
    </extension>

    What if I make make calls through my code recursively, how to record them all?

      you need to execute the application “record_session” on all of them. In this example, you select the calls for recording. If you need it for all calls, then the configuration is even simpler.

    The above dialplan is unable to record the outgoing call..And can u tell me can i record the conversation on each legs in different files??Howz it possible..I’ve checked it in Asterisk using monitor command,And i knew that in freeswitch we use record_session to do that.I am able to record both the conversations of users in a single file.But i want each of them in seperate files

      the above dialplan is actually recording the outgoing calls if they are prepended with a #.

      you can use sox for splitting the audio file if needed.

    Not using anything like sox.When the call has been established between two users,then each of their conversation should be recorded in 2 different files immediately after the call is hung up.

    hi. I faced with strange situation.
    I use command record_session in js file.
    Here is 2 lines from this file

    rec_f_name = ‘/var/www/recordings/’+new_session.uuid+’_rbt.wav’;
    new_session.execute(“record_session”, rec_f_name);

    In the end i got wav file with correct size and correct length, but there is no audio inside. Just silence.
    When I use command session.recordFile i got file with audio. It’s ok. But new_session.execute(“record_session” doesn’t work properly.

    I tryed to reinstall freeswitch from latest git.
    I turned of firewall.
    I checked settings.

    I don’t have any idea at all.
    Thanks for your help!
