Diameter - setting correct result code based on maxusage

[Anthony Somerset]

Hi There

i am attempting to return the correct result code (and granted service units too) based on the max usage, below is my current attempts at making it work:

        "request_processors": [

           {

               "id": "VoiceInit",

               "filters": ["*string:*vars.*cmd:CCR", "*string:*req.CC-Request-Type:1"],

                        "value": "0"},              

               ],

           },

unfortunately the *lte and *gt seem to be not having any match ever - have i referenced the MaxUsage incorrectly or something here?

Hi Anthony,

When you compare max usage in the filter you shouldn't use the converter, just *gte:*cgrep.MaxUsage:0 

Thanks,

thanks, when i tried that i was getting incomparable errors:

what i finally got working was something like this:

                    {"tag": "ResultCode",  "filters": ["*gt:*cgrep.MaxUsage:0s"],

                        "field_id": "Result-Code", "type": "*constant", "value": "2001"},

                   {"tag": "ResultCode",  "filters": ["*lte:*cgrep.MaxUsage:0s"],

                        "field_id": "Result-Code", "type": "*constant", "value": "5031"},

same for setting the CC-Time field too

when i get chance i will submit a PR to update the voice example here: https://github.com/cgrates/cgrates/blob/master/data/conf/samples/diamagent/voice.json
