I have a phone landline connection and I DO NOT have a phone instrument. I connect the cable into my laptop, and want to make calls using my laptop. I have an HDA CX20561 modem. I seem to be able to dial number using dialer.exe, though nothing seems to happen. From Microsoft kb http://support.Microsoft.com/kb/958143, it looks like dialer.exe alone is not enough for the call.
Can somebody tell me how to make and receive phone call with whatever hardware I have, I.e. what software will I need.
