I got the same problem, and what i change it was point-to-point to point-to-multi-point, and I used normal patch cable to connect the ISDN card to ISDN connector, and I used TE mode. In italy work like that I hope that will help you, I used also bristuff.

I know the configuration of telco is point-to-point and I think the card have to work in NT mode (I presume because I have not found the documentation about this and when attach to the ISDN the led become green). I'm not able to make and receive call. When I receive a call nothing happen in the asterisk cli and from the caller I receive a connection error. When I try to make a call I receive "unable to create zap channel" THis is my configuration: Zapata.conf switchtype = euroisdn signalling = bri_net pridialplan = local prilocaldialplan = local nationalprefix = 0 internationalprefix = 00 echocancel = yes context=default group = 1 ; S/T port 1 channel => 1-2 signalling = bri_net group = 2 ; S/T port 2 channel => 4-5 signalling = bri_net group = 3 ; S/T port 3 channel => 7-8 signalling = bri_net group = 4 ; S/T port 4 channel => 10-11 signalling = bri_net Zaptel.conf loadzone=it defaultzone=it span=1,1,3,ccs,ami span=2,0,3,ccs,ami span=3,0,3,ccs,ami span=4,0,3,ccs,ami bchan=1,2 dchan=3 bchan=4,5 dchan=6 bchan=7,8 dchan=9 bchan=10,11 dchan=12 Bye -------------- next part -------------- An HTML attachment was scrubbed...
