The setup program of a hardware manufacturer typically adds the new telephony service provider to the list on the Advanced tab of Phone and Modem Options. If a telephony service provider is not listed on the Advanced tab after you run the setup program, use this procedure to add the service provider. If it is not listed in the Add Provider dialog box, see documentation from the hardware manufacturer for further instructions.
