T56A/T58A door phone questions

[xgonc]

Hi,

Before buying, I wanted to check if this is doable:

a) when receiving a door phone call, display the video from a MJPEG HTTP stream source, and be able to preview the video before answering the call.

b) can the soft button to activate the relay door, be configured with a HTTP link instead of a on call code? The goal would be to open the door without answering the phone (when video is enough).

Is this possible on T56A or T58A?

Thanks.
