Hi,

I am using ISDN (PRI) for handling calls. In a use case we need Redirecting number as part of freeswitch events. I verified various events but we get only caller/called. I was looking into the code & found for SS7 this is available but not for ISDN, just need confirmation if any way possible to get this. I am using 1.2.24 (1.2.stable) freeswitch for testing.

following is ISDN SETUP message for reference:
