For private data CSTA requires that “Manufacturer specific (or standard) extensions shall be uniquely identified using Object identifiers issued by Ecma according to ISO 6523.” How do I get such an Object identifier?
Use http://www.oid-info.com/get/1.3.12.2 to add your company in the Ecma Object IDentifiers (OIDs) branch. Once registered your company becomes responsible for issuing OIDs under their own naming node. The need to check that an identifier does not already exist within the company cannot be stressed too much. The authority may charge “a reasonable fee” for this service.
