[SHR] Revealing/Hiding my caller id

seems the most sensible way.
when i call a hotline i don't want my number to end up in the database of  
some marketing dep of the company -- otoh when i call friends i want my  
number (resp my name, because i am in their address books) to be shown, so  
they know who call[s|ed].

> every cellphone I've owned, this is done in general: for all calls it is
> either hidden or shown to the receiving party.

does that mean we are not allowed to do something more flexible and  
sensible?
