I can attach screenshot of ISUP part of pcap.
Is it possible to extract all ISUP parameters or at least 'Redirecting number' or 'Called IN number'? Can extract ISUP part as is in binary form and read by some external script? Are you know about any library to parse ISUP binary data?

Hello,
can you provide a pcap (or ngrep output) with such invite in order to see what can be done with existing modules? Maybe it needs just some script operations.
Cheers, Daniel

Hi,
I need to extract ISUP parameter 'Redirecting number' from SIP-I INVITE request and add it as SIP header with 'X-' prefix to process in FreeSWITCH. I tried to read https://kamailio.org/docs/modules/5.1.x/modules/sipt.html (but it is about updating headers) and https://kamailio.org/docs/modules/5.1.x/modules/ss7ops.html (but I have only ISUP encapsulated in SIP), so not found any solution. Help me to find it please.
