Hi,
when to ip phones phone with each other via openser and i "pull out"
the network cable of both, the calls will never end in our cdr's,
because of the missing bye's.

You would have to use either:
- a B2BUAWM (B2BUA with media) which tears down the session if no RTP
packets are received for some time or
- a B2BUA with Session-Timer support which checks if the session is
still alive

Hi Martin,
You could use session timers. I think there is a draft (or already an
RFC??) about this issue. Both clients (or at least one client and the
SIP-Proxy) has to support this. The basic mechanism is the following:
The Client adds a "Session-Timer"-Header to the request. In this header
a timeout is defined. If both clients supports this, they have to do a
"Re-Invite" within this time to keep the connection alive. If there is
no "Re-Invite" the line is dead.
I would not try to look at the RTP-Stream, because in our cases the
RTP-Mediastream is happily directly between the Carrier (his Gateway)
and the client. Looking at the RTP-Stream is only pratical for smaller
solutions.
Greetings from Hamburg,
