Dial-Up Networking Uses Tone Dialing Instead of Pulse Dialing

In Windows XP, you can set up dialing rules and different locations from which to dial. One of the options that is available in each location is whether to use tone dialing or pulse dialing. Pulse dialing is required in some areas of the world because not all phone-switching equipment supports tone dialing. To use pulse dialing, you must set up a dialing location with pulse dialing selected. You must also configure your Dial-Up Networking (DUN) connection by using these dialing properties or the connection reverts to tone dialing.

After you create a DUN connection, you can edit its properties by right-clicking the connection, and then clicking Properties. On the General tab, there is an option to edit the phone number. There is also a Use area code and dialing rules check box. If this check box is not selected and you have dialing rules set to use pulse dialing, the connection tries to dial by using tone dialing.

There are two ways to use pulse dialing:

• Turn on Dialing Rules with a location set to use pulse dialing.
• Type P before the number. For example, P555-1212 instead of 555-1212.
