To modify an existing calling card

  1. Click Start, click in the Search text box, and then type TELEPHON.CPL and press ENTER. The Phone and Modem dialog box opens.

  2. In the Phone and Modem dialog box, on the Dialing Rules tab, click the location you want to modify, and then click Edit.

  3. On the Calling Card tab, click the card type you want to modify, and then click Edit.

  4. Click the General tab to change the calling card name, number, or your personal identification number (PIN).

  5. Click the Long Distance, International, or Local Calls tab to change the access number or dialing steps for the corresponding type of call.


When you enter a calling card PIN number, this number is displayed in plaintext. Therefore, to enhance security, type this number in a private location whenever possible. If you are not in a private location, make sure that this number is not exposed to another user.

Additional considerations

  • 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.

  • If you add Access Number, PIN, or Account Number to the Calling card dialing steps and the corresponding field is blank, Windows prompts you to enter the missing value when you click OK or Apply.
