Hello Jan Thanks for your reply. May you please advice how to check and conclude based on the CIC field and the PC. I am not in US so i presume the best option for me is ETSI as i am using ITU. Do i have to get it from the debugging or from the isup.c code? I cant see nothing on neither isup.c nor ss7.c nor their header files The problem is that Vodafone are failing to make a connection until the version issue has been cleared.
