Hi all, Thanks to the generous help from Mr. Pawel Ratajewski, I have managed to solve the initial alignment problem(was using the beta version 1.0.93 of chan_ss7 and it is solved by downgrading to 1.0.0 following some reboots). But I still couldn't get the ss7 link ready for making calls. All CIC are in 'idle reset pending' status. The below's is the log messages.
