Java Fax - Fetch the Image of a Submitted Fax

The GetFaxImage method, demonstrated in the following Java fax API snippet, retrieves the image of a previously-submitted, outbound fax.

The GetFaxImage code sample is also available as part of the ZIP file above (see the green 'Download' box), under the path interfaxJavaSamples > src > GetStatusWithFaxStatusEx.

This Java fax example retrieves the image of an outbound fax:
