Ditto, it could be a fun feature to have (being German and all).
However, I think that having a number that anyone can call that will
open the gate is even *worse* than having people get buzzed in and not
greeted. With such a system, responsible persons at the space wont
even know the gate was buzzed.

Unfortunately, it's not possible to accurately count (as a call
receiver) how many rings a caller has heard, especially in the case of
SIP. The ringing state is signalled and the ringing synthesized,
rather than being an audio stream that both ends can see.
