<scenario name="INVITE (optional auth), re-INVITE to T38 and send a Fax, Walter Doekes 2012-2013">

  <!--

  NOTE: Creating a sipp-sendfax.pcap is as easy as:
  - receive a fax with asterisk
  - get the incoming side of the spansdp.log (use 'fax set debug on',
    check your logger.conf)
  - feed it to spandspflow2pcap.py

  NOTE: sipp-sendfax.xml requires image pcap play support in SIPp. This
  means a version above 3.5.0, or the master git branch from
  https://github.com/SIPp/sipp.
