Hello, I require to calculate on hangup the duration of a call regardless of the CDR, and do some logic if it's above a range. I'm placing at the api_hangup_hook a cli parameters that one of them is answered_time. I need the data in minutes unit, and the data seems to be a timestamp in microseconds, but converting it to seconds (e.g. answered_time / 1000000) provides me a very low range of number, sometimes even less then a millisecond. I can't seems to find at the documentation what is the unit for the answered_time in order to properly convert it to my requirements. I'm also missing the place at the source code where the data is set to the variable (here is the grep result (at the src directory): grep answered_time ./* -R ./mod/event_handlers/mod_cdr_mongodb/mod_cdr_mongodb.c: bson_append_long(&cdr, "answered_time", caller_profile->times->answered); ./mod/languages/mod_managed/managed/ChannelVariables.cs: const string answered_time = "answered_time"; ./mod/languages/mod_managed/managed/ChannelVariables.cs: get { return readUsecsDateTime(answered_time); } ./switch_caller.c: if (!strcasecmp(name, "answered_time")) { ./switch_core_session.c: } else if (!strcmp(tag3->name, "answered_time")) { ./switch_ivr.c: if (!(time_tag = switch_xml_add_child_d(x_times, "answered_time", t_off++))) { ./switch_ivr.c: cJSON_AddItemToObject(j_times, "answered_time", cJSON_CreateString(tmp)); So what am I missing here? Thank you Ido
