Dial-Up Networking Cannot Dial Local Area Code

When you install TAPI (Telephony Application Programming Interface) 2.1 and configure a Dial-Up Networking connection to use the local area code when you dial a phone number, the 10-digit phone number to be dialed may be changed to contain random or unintelligible characters.

This behavior occurs because the Tapi32.dll file that is installed with the TAPI 2.1 software cannot correctly handle the 10-digit local area code and phone number.

To work around this issue, follow these steps:

1. Double-click the Dial-Up Networking connection you want to use, and then click Dial Properties.
2. Type 000 in the Area Code box, and then click OK.

When you type 000 in the Area Code box, the correct local area code is dialed, but the number to be dialed does not contain any invalid characters.

This problem no longer occurs in Windows 98. To resolve this problem, install the current version of Windows. For information about the current version of Windows, visit http://www.microsoft.com/windows (http://www.microsoft.com/windows) .
