Hi! I want to signal two call numbers during the setup of a ss7 call. In addition to the network provided number (flag 0x13) I want to transmit a userprovided, not screened number (flag 0x10) In order to do this, I wrote a patch for l4isup.c in chan_ss7 which inserts a new optional isup header in the IAM right behind the calling party number header. This works quite well, I traced a few testcalls which looked as proposed. But trying to get the working in a live environment I discovered that our carrier is dropping every calls which includes the two numbers. Does anybody know if this is an issue about ss7 ?! In the ss7 docs the flag for userprovided, not screened (0x10) is said to be "reserved for national use". What does that mean ? Could that be the reason for the dropped calls ? I am quite new to ss7, so I am a very confused about this. Maybe someone can help me. Oliver
