In the "Server notice" room, the call button is clickable.

### Steps to reproduce

Enter the "Server notice" room and observe.

### Outcome

#### What did you expect?
Since I don't have any sending permissions in this room, these buttons should, in principle, be disabled for me.

#### What happened instead?
The call button is clickable, but since I don't have speaking permissions in this room, enabling it makes no sense.
