Other Connection Information

The members of the RASDIALPARAMS structure can also specify the following connection information:

• A phone number to override the number in the phonebook entry.
• A callback phone number that the remote server can call back to establish the connection.
• The name of the remote network domain on which the authentication is to occur.

For the callback number and the domain, the RASDIALPARAMS members can either indicate that RAS should use the information in the phonebook entry, or it can provide information that overrides the phonebook data.

A RAS client can use the lpRasDialExtensions parameter of the RasDial function to control whether RAS uses a phone number prefix or suffix specified in a phonebook entry.
