Add a new upload specification to any existing Spring bean file. For example
sipXconfig/neoconf/src/org/sipfoundry/sipxconfig/phone/phone.beans.xml

  <bean id="polycomFirmware"
    class="org.sipfoundry.sipxconfig.upload.UploadSpecification">

    <!-- Use upload spring bean -->
    <constructor-arg value="upload"/>

    <!-- Directory to find upload.xml file -->
    <constructor-arg value="wayCool"/>

    <!-- Label -->
    <constructor-arg value="Way Cool Device"/>

  </bean>

...

Step 2:Describe upload files

Create following file
sipXconfig/neoconf/etc/wayCool/upload.xml

<?xml version="1.0"?>
<!DOCTYPE model PUBLIC "-//SIPFoundry//sipXconfig//Model specification 2.0//EN" 
  "http://www.sipfoundry.org/sipXconfig/dtd/setting_2_0.dtd">
<model>
  <group name="firmware">
    <label>Firmware</label>
    <description>Firmware for Way Cool Device</description>
    <setting name="wayCoolFirmware.dat">
      <label>wayCoolFirmware.dat</label>
      <type><file><contentType>application/binary</contentType></file></type>
      <description>Firmware binary.</description>
    </setting>
  <group>
</model>

• You can write your own code to deliver or process the uploaded files. Extend Upload.java, add an entry in Spring file similiar to Spring bean "upload". Change the first argument of the upload specification entry to your spring bean name.
• Declare firmware, ring tones, dial plans, directories, etc, in your upload.xml file. Break into logical groups for better presentation in web UI.
• To add support for multiple firmware versions, you can create a series of upload.xml files to organize and extend other versions, much like phone.xml and line.xml files. For example:
  sipXconfig/etc/wayCool

  Panel
  upload.xml – all firmware files upload_3.x.xml – describe firmware files unique to version 3.x upload_4.x.xml – describe firmware files unique to version 4.x
