Hello, I cannot block CallerID with attila's libss7. I've two crossed boxes with the same software version and specular configuration. I had some checks with "core show channels verbose" inside Asterisk, and with a protocol analyzer (showing Calling Party Number with Presentation Allowed) My setup: [[[extensions.conf]]] ... exten => 03312,1,Set(CALLERPRES()=prohib) exten => 03312,n,Set(CALLERPRES(num)=prohib) exten => 03312,n,Set(CALLERPRES(name)=prohib) exten => 03312,n,Dial(DAHDI/g1/${EXTEN}) ... [[[chan_dahdi.conf]]] [trunkgroups] [channels] echocancel=yes echotraining=no context = default signalling = ss7 ss7type = itu ss7_called_nai=dynamic ss7_calling_nai=dynamic usecallerid=yes hidecallerid=no callerid=asreceived group = 1 linkset = 1 pointcode = 10 adjpointcode = 9 defaultdpc = 9 ... Anyone has suggestions? Thank you! Mario -------------- next part -------------- An HTML attachment was scrubbed...
