VP530 - Disabling my face while in standby + Doorphone volume

[Mauro]

Hi! We've just tested or first VP530 phones.

We are trying to guess about two things:
- Is there a way to prevent the phone from showing me my own face while in standby mode (while not calling)? E.g. by turning it on/off by pressing the webcam key, or just having it completely disabled until you actually are in conversation?
Having that small monitor showing me my own face the whole time is somehow disturbing... it gives me a sort of "big brother" sensation!

- We have configured the "door phone" parameters, so when the 2N IP Intercom calls the VP530, the "button" to "open door" appears. But during that conversation, we have not been able to modify the volume level on the VP530 (left and right keys -normally used to change volume during "standard" calls- do not work).

VP530 firmware is 23.70.0.40.
Is there a way to do such operations? If not, please take in account to add such features in future firmware updates. Thank you!

PS: Is it possible to set the webcam as disabled by default while calling, requiring me to press the webcam key to enable it? I mean, if I want to be seen only when I really want.
