When using the Sage CRM API to retrieve phone records, it returns the association URLs for getting associated company/person records. These do not work, though, and return no results when called. 

Does anyone know why this is or if there is a way to fix it? Is it a bug in this Sage CRM version (2023 R2.1)?

Example Response for Phone endpoint:

{
    "$key": 757938,
    "$title": "",
    "$url": "http://srv-apps/sdata/crmj/sagecrm2/-/Phone('757938')",
    "Phon_CountryCode": "44",
    "phon_IntId": null,
    "Phon_number": "123456",
    "phon_promote": false,
    "Phon_AreaCode": "0811",
    "phon_segmentid": null,
    "phon_IntForeignID": null,
    "phon_intlastsyncdate": null,
    "Person": {
        "$url": {
            "Association": "http://srv-apps/sdata/crmj/sagecrm2/-/Phone('757938')/Person?startindex=1&count=10"
        }
    },
    "Company": {
        "$url": {
            "Association": "http://srv-apps/sdata/crmj/sagecrm2/-/Phone('757938')/Company?startindex=1&count=10"
        }
    },
    "Account": {
        "$url": {
            "Association": "http://srv-apps/sdata/crmj/sagecrm2/-/Phone('757938')/Account?startindex=1&count=10"
        }
    }
}

Response from the association URLs in the above example:

{
    "$url": "http://srv-apps/sdata/crmj/sagecrm2/-/Phone('757938')/Company?startindex=1&count=10",
    "$first": "http://srv-apps/sdata/crmj/sagecrm2/-/Phone('757938')/Company?startindex=1&count=10",
    "$last": "http://srv-apps/sdata/crmj/sagecrm2/-/Phone('757938')/Company?startindex=1&count=10",
    "$totalResults": 0,
    "$startIndex": 1,
    "$itemsPerPage": 10,
    "$resources": []
}
