Hi all, I am exploring the use of the ims_charging module having set up a freediameter server (all very new to me). I have loaded and configured the dependencies i.e. cdp, dialog_ng, tm, cdp_avp but the startup gets stuck on: Jan 26 03:57:05 host-172-16-0-82 /usr/sbin/kamailio[2931]: ERROR: ims_charging [mod.c:269]: mod_init(): Could not import ul_register_ulcb Jan 26 03:57:05 host-172-16-0-82 /usr/sbin/kamailio[2931]: ERROR: <core> [sr_module.c:968]: init_mod(): Error while initializing module ims_charging (/usr/lib64/kamailio/modules/ims_charging.so) The corresponding code in mod.c is: /*Register for callback of URECORD being deleted - so we can send a SAR*/ if (ul.register_ulcb == NULL) { LM_ERR("Could not import ul_register_ulcb\n"); return -1; } But unfortunately this doesn’t mean much to me – what is a URECORD, what is a SAR? Any words of wisdom around what a “ul.register_ulcb” is about would be appreciated.
