Hi list, on my asterisk machine I have an E1 (Beronet with chan_misdn) board and sip clients connected. I am getting some AAI (application-to-application-information, enriched SIP header, similar to the SipAddHeader application) from a sip client during the BYE method. I want to give this AAI to my ISDN line as UUI (user-to-user-information) during ISDN Hangup. Doing that with the SipGetHeader application is not possible as this is only allowed on incoming SIP calls. Is there a possibility I can customize my cdr in a manner that logs this AAI and I can strip that in the hangup extensions from the cdr to set the MISDN_USERUSER variable and write UUI? TIA and Regards, Christophorus
