FreeSWITCH documentation is primarily hosted by the team at SignalWire. While there isn't a single official "book-length" PDF download provided by the project for the entire software, most users refer to the FreeSWITCH Cookbook or the official Wiki.

  • PDF Generation: Most modern documentation sites allow you to export pages to PDF. If you need a specific section (like the Dialplan or Directory) as a PDF, look for the "Export to PDF" button on the specific Wiki page.

    • In /etc/freeswitch/directory/ create hotdesk_users.xml:

    <include>
  <user id="101" mailbox="101">
    <params>
      <param name="password" value="1234"/>
    </params>
    <variables>
      <variable name="user_context" value="hotdesk"/>
      <variable name="effective_caller_id_name" value="Alice Sales"/>
      <variable name="email_pdf" value="alice@company.com"/>
    </variables>
  </user>
</include>

    Here is a snippet of the modern "hot" dialplan logic that developers are deploying today:

    <extension name="pdf_invoice_hotline">
  <condition field="destination_number" expression="^(1234)$">
    <action application="set" data="pdf_template=/var/templates/invoice.html"/>
    <action application="set" data="sql_query=SELECT * FROM orders WHERE caller_id=$caller_id_number"/>
    <action application="lua" data="db_to_json.lua"/>
    <!-- The "Hot" part: Generate PDF in memory, don't write to disk -->
    <action application="pdf:generate" data="/tmp/hot_invoice.pdf $pdf_template $json_data"/>
    <action application="fax:send" data="tiff:///tmp/hot_invoice.pdf $fax_destination"/>
    <action application="system" data="rm /tmp/hot_invoice.pdf"/> <!-- Cleanup -->
    <action application="playback" data="ivr/your_invoice_is_ready.wav"/>
  </condition>
</extension>

    While later versions focused on WebRTC and clustering, FreeSWITCH 1.8 hit a "sweet spot" for developers who need bare-metal PDF handling. freeswitch 18 pdf hot
