Privacy - webclient shows numbers of all call participants of everyone

[nobody]

While it is good to see the status of an extension (availiable/away/in a call), it might not be desirable that everyone sees the number of an active call an extension is currently engaged.
AFAIK, the Windows client only shows an extensions status, not the number of the call. But the WebClient displays the number of the call.
Can this be disabled by user or group?

you shall be able to control this via those group right options

The windows client in the switch board view shows the same information btw...
