To assign multiple phone numbers to a dial-up connection

If your computer is connected to a network, network policy settings might prevent you from completing these steps.

Click to open Network Connections.

Right-click the dial-up connection that you want to configure, and then click Properties.

On the General tab, click Alternates, and then do any of the following:

To have the connection try a different phone number if the first number in the list is not successful, select the If a number fails, try the next number check box.

To have the connection move the first successful phone number to the top of the list under Phone numbers and use it on the next connection attempt, click Move successful numbers to top of the list.

To add a new phone number to the list, click Add, and in Phone number, type the phone number.

To change the order of phone numbers under Phone numbers, click a number, and then click the arrows until the phone number is in the correct order.

To remove a phone number under Phone numbers, click the number, and then click Delete.

To have the connection use established area code and dialing rules, on the General tab, select the Use dialing rules check box.

Tip
If you have alternate phone numbers defined for a connection, you can specify a particular phone number at the time you make your connection.

 To enable operator-assisted calls or manual dialing
If your computer is connected to a network, network policy settings might prevent you from completing these steps.

Click to open Network Connections.

Select the dial-up connection, press the Alt key, click the Advanced menu, and then click Operator-Assisted Dialing. (If operated-assisted dialing is already enabled, Operator-Assisted Dialing on the Advanced menu is selected.)

Double-click the connection that you want to dial.

Pick up the telephone, and then dial the number or ask the operator to dial it for you. The number assigned to the entry is displayed in the dialog box for easy reference.

Immediately after you finish dialing, click Dial on the connection dialog box.

Hang up the phone after the modem takes control of the line (you'll hear a click followed by silence).
