[Asterisk-Users] Asterisk does not disconnect SIP call

my situation is the following: I have an ISDN telephone connected to a
HFC ISDN card on an asterisk server. The asterisk server is behind a
NAT, but all the ports (i.e. 5060 and the range specified in rtp.conf)
are forwarded to the asterisk machine. I am using the German SIP
provider Sipgate.de. The sip commands show that I am registered properly
My problem is that when I want to call via the Sip provider a real phone
number (ISDN phone >> SIP), I get a ring tone. When I now decide to hang
up (f.e. when nobody answers), the called telephone continues to ring
forever. This error shows up:
"app_dial.c : 362 wait_for_answer: Unable to forward frame"
If the other party answers and I am the first one to hang up, the call
sometimes does not get cancelled as well. The called party has to hang
up first to really disconnect the call. This error is not yet
reproducable, as I said, sometimes it works and asterisk hangs up correctly.
I am using the lastest cvs version of asterisk that automatically
installs with the install script of the brifstuff von www.junghanns.net.
Any suggestions how to solve it?
