[Asterisk-Users] Asterisk doesn't disconnect when I hang up SIP (SIP -> PSTN call)

[Tomasz Chmielewski]

I'm trying to learn Asterisk.

So far I'm using kphone and an ISDN line (with Eicon DIVA 2.01 PCI card).

I have created that extension following The Asterisk Handbook (page 36):

[ext-local-custom]
exten => _0.,1,Dial(Modem/ttyI0:${EXTEN:1})
exten => _0.,2,Dial(Modem/ttyI1:${EXTEN:1})
exten => _0.,3,Congestion


So whenever I call 055 from kphone, Asterisk connects me to an internal 
55 number, and I can talk to myself (wohoo!) when I pick up the phone.

However, when I call 055 from kphone, and *don't* pick up the phone on 
the other side, and then disconnect kphone (or even quit it), asterisk 
keeps ringing 55.

I'd like to add, that Asterisk detects kphone disconnecting when the 
phone is already established.

Any clue?
