I have a VTO2311R-WP door station. I install the DMSS app on my Samsung Galaxy Ultra 23 android phone. When I add the VTO with its ip address, my phone gets notification when door bell is pushed. If I add the VTO via P2P, notification doesn't work. Is there anything I need to set in order to get notification when the device is added via P2P? It's interesting to note that when the VTO is off, my phone will get notification when the device is added via P2P.
