Hi, I cannot arrive to understand how Asterisk uses LIBSS7 to place ISUP calls since I do not find any code in Asterisk that uses LIBSS7. I understand that LIBSS7 can use DAHDI drivers to send and receive data from DAHDI hardware as implemented in ss7test.c and ss7linktest.c. But, in Asterisk code I don't find any call to LIBSS7 to place an ISUP call. Can you please clarify that to me. Thank you. -------------- next part -------------- An HTML attachment was scrubbed...
