Active calls remain in progress untilthey return to on-hook. The default value for this parameter is Enabled.Fax SupportedThis specifies whether or not faxes will be transmitted on the port. If No isselected, all calls will be treated as voice. If Yes is selected, both voice and fax willbe transmitted.
