Cannot Change TAPI Dialing Rules in Windows 98

ID: Q217189

The information in this article applies to:

Microsoft Windows 98

SYMPTOMS

Microsoft Windows 98 includes Windows Telephony and the Telephony API (TAPI) version 2.1. One of the features of Windows Telephony is the ability to automatically use the correct outside line access codes, long distance and international prefixes, and other dialing rules based on your location and the destination of a telephone call. You specify most of this information in Dialing properties using the Telephony tool in Control Panel and in most programs that place telephone calls. Windows Telephony includes dialing rules for local, long distance, and international calls for over 240 different countries around the world; these rules are stored in the registry.

From time to time, countries change their dialing rules. If the dialing rules for a country or region change, Windows 98 does not dial it correctly.

CAUSE

The Windows 98 Telephony components do not allow the telephony dialing rules to be updated by settings in a configuration file (.ini file) or in the registry.

If these values in the registry are changed, the Windows 98 Telephony Server component (Tapisrv.exe) overwrites the changed registry values with the original default values.

Methods for Working Around the Default Behavior

Local, Long Distance, and International Dialing

For local dialing, you can click to clear the "Use country code and area code" check box to make Windows dial the number you enter in the Phone Number box exactly as you enter it. Dialing properties (such as call waiting and outside line access numbers) are not applied.

This check box appears in the Dialing properties for Dial-Up Networking or HyperTerminal connections, or are normally accessible through dialing programs that use the Windows Telephony API (TAPI).

For example, in Dial-Up Networking, right-click the connection that you want to modify, and then click Properties to modify the Dialing properties. The "Use country code and area code" check box appears on the General tab.

When you use this method you must enter every digit that is to be dialed in the Phone Number box. The digits are not automatically adapted as you change locations, but you have complete control over the number that is dialed.

You can use this method with HyperTerminal, Dial-Up Networking, and MSN, The Microsoft Network.

Long-Distance or International Dialing Only

For long-distance or international dialing, you can work around this behavior by creating a custom calling card rule that uses the correct dialing rules for the country whose rules are incorrect.
