[Asterisk-Users] Hang up not hanging up (New Zealand Indications??)

[Simon]

Hi there,

I have a new asterisk working in New Zeland and everything is working 
well except when an incoming call to the PSTN hangs up, asterisk wont 
hang up the zap trunk (X100P).

I have found this information:
http://bugs.digium.com/bug_view_page.php?bug_id=0001474

Which discusses my problem and i have made sure that i have the latest 
info in the indications.conf as follows:

[general]
country=nz

[nz]
description = New Zealand
;NOTE - the ITU has different tonesets for NZ, but according to some 
residents there,
;      this is, indeed, the correct way to do it.
ringcadence = 400,200,400,2000
dial = 400
busy = 400/250,0/250
ring = 400+450/400,0/200,400+450/400,0/2000
congestion = 400/375,0/375
callwaiting = !400/200,!0/3000,!400/200,!0/3000,!400/200,!0/3000,!400/200
dialrecall = !400/100!0/100,!400/100,!0/100,!400/100,!0/100,400
record = 1400/425,0/15000
info = 400/750,0/100,400/750,0/100,400/750,0/100,400/750,0/400
stutter = 
!400/100!0/100,!400/100,!0/100,!400/100,!0/100,!400/100!0/100,!400/100,!0/100,!400/100,!0/100,400

But it still wont hang up. Any thoughts where i can begin on this one?

Thanks
