| ------------------- | -------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `isGlobal`          | boolean  | Set to `true` to return directory numbers from the global call center, or `false` to return directory numbers specific to a call center.                                                                                                                                                                                                                                               |
| `callCenterName`    | string   | Specifies the call center name on which to return directory numbers. If `isGlobal` is `false` and this field is not specified, all directory numbers are returned.                                                                                                                                                                                                                     |
| `callback`          | function | JavaScript method executed when the API method call is completed.                                                                                                                                                                                                                                                                                                                      |
| `resultSetPage`     | integer  | Represents the page number of the list of results to return. This number starts at 0.                                                                                                                                                                                                                                                                                                  |
| `resultSetPageSize` | integer  | Sets the maximum number of phone numbers to retrieve. Defaults to 5000; maximum is 10000. If `hasNext` returns `true` in the `callback`, use this argument with `resultSetPage` to get the next page of results. For example, if `resultSetPageSize` is 5000 and `resultSetPage` is 0, the first 5000 phone numbers are returned; if `resultSetPage` is 1, the next 5000 are returned. |

                   alert(response.error);
           }
        };

       var isGlobal = false; //Do not return directories from the global call center
       var callCenterName = 'My Call Center'; //Call center name of directory numbers to return

       function getDirectoryNumbers() {
                sforce.interaction.cti.getDirectoryNumbers(isGlobal, callCenterName, callback);
