I am working in Production App, and try to get Active Calls. the field I need is ExtensionNumber from response. but it was empty in response. I login in with company main Number and request is: "https://platform.ringcentral.com/restapi/v1.0/account/~/active-calls?view=Detailed";
I even tried "https://platform.ringcentral.com/restapi/v1.0/account/~/active-calls"; still no luck.
why can't I get extension Number in response?
