[asterisk-users] PRI (Primary-NTT)

[Don Kelly]

Your carrier is apparently using a Japanese switch (at least it's a Japanese
standard).

If you don't get a good answer from the list, you might send an email to
louis.leclerc at denphone.com. Denphone is a company installing Asterisk
systems in Tokyo.

hi folks.

i recently setup an Asterisk system in Hong Kong. their phone
company told me that their T1 PRI switch type is Primary-NTT.
however in chan_dahdi.conf there's no such option. i have it
set to national. it worked fine for a while, but now suddenly
stop working. in coming call just keep ringing and didn't
even show up on console. out going call hang up immediately
with cause code 27. (as usual, phone co. just said it's
problem with our equipment without giving us any detail).
anybody have any suggestions?

here's our /etc/dahdi/system.conf:
loadzone=hk
defaultzone=hk
span=1,1,0,esf,b8zs
bchan=1-23
dchan=24
span=2,0,0,esf,b8zs
bchan=25-47
dchan=48
span=3,0,0,esf,b8zs
bchan=49-71
dchan=72
span=4,0,0,esf,b8zs
bchan=73-95
dchan=96

/etc/asterisk/chan_dahdi.conf:
switchtype=national
pridialplan=unknown
prilocaldialplan=unknown
internationalprefix = 001
