[asterisk-users] long busy()

[Christophorus Laube]

hi list,

I set up a new asterisk machine with asterisk 1.2.13 and misdn 0.3.1rc27.
I use an e1 card with sip clients. My extensions look like this:

[E1]
<snip>...<snip>

exten => 33006733,1,Set(CALLED=${EXTEN})
exten => 33006733,2,Dial(SIP/1 at 192.168.0.23)
exten => 33006733-ANSWER,3,Answer()

[SIP]
exten => _X.,1,Noop()
exten => _X.,2,SetCallerPres(allowed_passed_screen)
exten => _X.,3,Dial(mISDN/g:E1/${EXTEN},40)
exten => _X.-BUSY,4,Busy(1)

But whenever a sip client calls to an exten that is busy through e1 I get busy 
tones for 10s before I get disconnected. But I want to have it only for 1s.
Does anyone know how to fix that?
regards, Christophorus
