# getDirectoryNumbers() for Salesforce Classic

## Usage

Returns the list of phone numbers from the call center's directory. This method is only available in API version 31.0 or later.

## Syntax

```javascript
sforce.interaction.cti.getDirectoryNumbers(isGlobal:boolean, callCenterName:String, (optional) callback:function, (optional) resultSetPage:Integer, (optional) resultSetPageSize:Integer)
```

## Arguments

|Name|Type|Description|
|------|------|-------------|
|`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.|

           }
        };

       var isGlobal = false; //Do not return directories from the global call center
