Hi All,

Dialog2 is a start at the following: http://www.kamailio.org/dokuwiki/doku.php/modules-new-design:dialog-module-design

We needed this functionality for the IMS modules. In IMS a proxy can take the same session in both terminating and originating modes (ie 2 dialogs for the same session). dialog 1 does not support this. Dialog2 has been tested to at least support the functionality we required and we will build on it as we move along.

Docs are coming but please be patient - we are really busy at the moment, not just with ser/kamailio.
