Before you begin
If you are importing a .csv file created using Microsoft Excel, ensure that the file does not contain any additional characters. To do so, open the file in any other text editor. For example, if you add the string GROUP;ADMINISTRATORS;SIP_CONTROLLER_LIST;"127.0.0.1:5061;transport=TLS" using Microsoft Excel and then open the file in a text editor, you will see that the string now contains some additional quotation marks: "GROUP;ADMINISTRATORS;SIP_CONTROLLER_LIST;""10.255.249.144:5061;transport=TLS""". You must remove any additional characters. Otherwise, bulk import will fail.
