FexEX Registration Set Up - Unauthorized delimiters in phone number

In entering a phone number in the  FedEx Registration window (under Setup/Accounting/Shipping/FedEx), the format defaults to a dot delimiter between the group of three-digit numbers; however, pressing the "submit" button triggers a message "The Phone field must only contain digits, spaces, and the dash character (-)." How could I have NetSuite accept any of the authorized delimiters (and not default to the unauthorized dot delimiter) when entering phone numbers in FedEx Registration?


I tried entering a space, a dash and no delimiter, to no avail. In every instance, Net Suites automatically defaults back to dot delimiters, and then prevents from "submit"ing, invoking the message "The Phone field must only contain digits, spaces, and the dash character (-)."
