Grandstream WP810 Wifi-Phone - Mobotix T25 Feed

Hey guys,

someone able to help me with setup of the Grandstream WP810 Wifi Phones to show video of the T25 when ringing?

I could let them ring and if i type manually #1 (or 1#) then the door opens. But i like to see the video and if possible to have a shortcut to open the door.
