Ok, but how is that supposed to work?
I read something that only G.711 is used here in Germany and so I should
not get a call with a G.722 codec.

The phone doesn't ring when I get such a call (where I supect that this
is 'spam' since I don't see a caller id).
Does the NetBSD isdn driver reject such calls, so the also connected
isdn phone doesn't get it?
