Crestron Home (RAVA) Integration?

How do we encourage Mobotix to work with Crestron to get the T26 door stations to support RAVA (superset of SIP) and RAVA call groups, as well as SIP early video (video before the call recipient answers) on the T26 and beyond? 2N has RAVA support, and obviously Crestron lists them as a direct integration, but their hardware and camera quality leaves a lot to be desired. Being able to use Mobotix cameras on these Crestron Home installs would be amazing.
