The second problem is the PSTN-Gateway. If I call a number through the
PSTN gateway and than hangup before somebody answers the called phone
will not stop to ring. How comes this?

Probably a call-progress problem. The PSTN gateway probably hasn't
detected that the incoming call has ended. If it is an analog gateway,
you need to look into call-progress tones. The telco switch should send
CP tones, but depending on where you live (there are several CP regional
standards), you might be out of luck. Check your PSTN gateway manual.
If it is a digital (PRI/BRI) gateway, end of call detection should be
automatic.
