[Asterisk-Users] ZyXEL Prestige 2000W SIP hangup fails

[Dominique Kull]

Does anybody have any experience with the ZyXEL Prestige 2000W? I am 
having problems with the line tear down when I call another extension. 
If nobody picks up at the other end when I hangup the 2000W, the other 
extension continues to ring. Is there any way to hangup a SIP call if 
there is no more traffic? Asterisk seems to think that there is still a 
connection open. This is pretty annoying since it always leaves an empty VM.

thanks
Dominique
