But, I need to access it from the Kamailio script so that I can lookup the credentials for that realm and then call uac_auth. I’ve tried getting the info from $ar, but that gives me the realm of the inbound request versus the realm of the upstream carrier. Also, I’ve tried using $T_rpl($ar), but that returns 0.
