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 nationalprefix = unknownprefix = signalling=pri_cpe usecallerid=yes usecallingpres=yes echocancel=no echocancelwhenbridged=no group=1 callgroup=1 pickupgroup=1 faxdetect=incoming context=pri_in channel => 1-23 -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
