i found one problem!!
so plz help me
when the caller send more than 16 digits, the MSC (mobil switch center) send
me (asterisk+libss7) in the IAM message only 16 digits and the others in the
SAM message. So asterisk got less digits that required for make a correct
call.
In the documentation appears "Basic call messages (IAM, ACM, ANM, REL, RLC)"
and not SAM, so i'm confused trying to find a solution (i'm not a C
developer yet). I'm going now to recompile actual sources.
here is a portion of ss7 debug

Asunto: libss7 under production
Hi i'm glad because now at this moment, we put asterisk version
SVN-trunk-r115509M + libss7(r159) under heavy production. And works very
very good. The other side of ss7 signalling is a ZTE MSC model ZXG10 (yes
we are a gsm telephony company). This asterisk is used to manage the call
duration from our gsm clients when they call other gsm companies or long
distance calls. For this reason we always have at least 30 cics busy and in
the peak hour about 120 cics (we have a TE410P). The system use
Agi+php+dialplan to work on define the call duration.
The only problem i 've is one segfault that makes asterisk restart once, if
happen again i going to recompile asterisk to support debug and kernel
symbols to find the problem
#dmesg
asterisk[17639]: segfault at 000000100e15cba0 rip 000000000044b117 rsp
0000000040c653c8 error 4
Hope my experience help other people and i want to say thankyou to all
people who works on libss7
Best regards
