+Mingle works by having all participants in a conference announce the
+definitions of the content that they provide in their MUC presence. This is
+used to build a global payload type (PT) mapping for the various contents,
+which is then used to initiate normal Jingle sessions. The global mapping
+allows each participant to encode and payload each content only once.
