I may be poorly explained the problem...

We have a paid call UA1 <-> UA2. UA1 pays UA2 for the connection. RTP goes in both
directions though a media relay. Imagine, UA1 crashes (softphone crashed
or network problem) and does not send a BYE message. Now, the flow goes
in one direction UA2 -> UA1. UA1 continues to pay the money (until UA2 has
disconnected).

Why media relay does not detect this call (connection) as expired? No
support in the conntrack library?
