Specify numbers to dial an outside line
Applies To: Windows Server 2008, Windows Server 2008 R2, Windows Server 7
You can use this procedure to configure the digits that have to be dialed to reach an outside line. This is commonly used to insert an '8' or '9' before the phone number when dialed on a private phone system, such as in a hotel or a place of business.
Any user account can be used to complete this procedure.
To specify numbers to dial an outside line
Click Start, click in the Search text box, and then type TELEPHON.CPL and press ENTER. The Phone and Modem dialog box opens.
In the Phone and Modem dialog box, on the Dialing Rules tab, click the location you want to modify, and then click Edit.
Alternatively, to create a new location, click New.
On the General tab, in Dialing rules, type the numbers required to reach an outside line for local and long distance calls.
You can also access the Phone and Modem Options dialog box from the Properties page of any of your dial-up connections. On the General tab, select the Use dialing rules check box, and then click Dialing Rules.
Do not use this procedure to specify the numbers required before dialing to a different city, area, or country/region, such as 1, 0, 00, or 011. The numbers specified here are to dial local or long distance calls from within a private branch exchange (PBX), such as used by a company or other organization.
