# create a client using the InterFAX WSDL
client = Savon::Client.new("http://ws.interfax.net/dfs.asmx?wsdl")

# execute a request to the :get_fax_image action
# this example uses a shortcut to set the SOAP body
response = client.request(:int, :get_fax_image, :body => {
  :username       => "your username",
  :password       => "your password",

# translate the response to a Hash and get the image
image = response[:get_fax_image_response][:image]

# decode the image data
image = Base64.decode64(image)

# save the image to disk
File.open("/Users/username/Desktop/fax.tif", "w") { |f| f.write(image) }
