1th: try my libss7/chan dahdi branch 2nd: define and use prefixes to set nai -- eredeti ?zenet -- T?rgy: [asterisk-ss7] Problem with CGB/CGBA and NAI Felad?: Bartosz Supczinski <Bartosz.Supczinski at dir.pl> D?tum: 2009.03.27. 17:57 Hi, I've set up an SS7 link, the connection works in both directions but I have 2 problems which I am not able to solve. I don't knot even if it's an Asterisk, Dahdi or libss7 issue or maybe the configuration or the software environment. The second problem is being encountered by other people too. I've found some descriptions, but unfortunately none of them contained a solution. * The first problem is about blocking a group of channels. During some tests with telecom it occured that when telecom blocks a group of channel Asterisk gets a "CGB" and it replies "CGBA", and despite of that Asterisk is trying to get through the blocked channels by sending "IAM". From the superior tel. exchange it gets "BLO" and replies "BLA" and after that it starts to treat the channel as a blocked one and doesn't occupy it anymore. The above error doesn't allow passing the compatibility tests, which are required by telecom. * The second problem is about "NAI", no matter how I configure "ss7_called_nai" and "ss7_calling_nai" Asterisk sends "Nature of address: 0" in "IAM", even when NAI = "dynamic" is set. I've managed to correct this by forcing settings in "chan_dahdi.c" - ss7_called_nai = p->ss7->called_nai; + ss7_called_nai = SS7_NAI_NATIONAL; - ss7_calling_nai = p->ss7->calling_nai; + ss7_calling_nai = SS7_NAI_NATIONAL; Nevertheless it is unacceptable, because telecom expects "NAI=3" while doing national calls and "NAI=4" with international calls. Maybe somebody would be interested in these problems and may help me solve them.
