How can I use Dragon naturally speaking to make and receive landline phone calls

I've got some 5 1/4" floppies if you need some. I've also got some 8" floppies that I'm not parting with

I wrote a program to monitor my calls that uses the caller ID info that comes in on the phone line to accept or deny certain numbers or partial numbers. In the process of doing that on Windows 2000 I learned that a voice modem will also extract the caller ID so I used that method.

When I upgraded to Windows 7 I couldn't find drivers for that old modem so I had to get a new one. This was in 2009. What I got was a Zoom Model 3095 56K USB Modem. It works fine with Windows 7 and Uverse VOIP. There is a USB pigtail on one end and a female jack for a phone line on the other end.
Here's a listing at Amazon

I initially had DSL so it needed a splitter but I recently switched from DSL to Uverse VOIP and it works OK with that without the splitter. The phone line that comes out of the Uverse gateway can be connected to regular touchtone phones so it's just a matter of going from the gateway phone jack to the standard house wiring that is already installed. The gateway handles all of the bidirectional VOIP stuff and it just looks like a phone line to the phone or modem.

I had one issue with Uverse that stumped me for a while but it was a wiring issue. My house was a builder's model and they had their sales office in the house and their construction office in the detached garage. The DSL system had two lines coming off of the same connectors - one for the house wiring and one for the garage wiring. When the Uverse was hooked up the DSL was disconnected so their was only one wire going to the gateway in the house which left the garage wiring disconnected. Once I figured out what was going on all I had to do was run a regular twisted pair phone line to the garage from the house wiring to the garage and the modem worked fine after that.

Basically what you need is an interface between Dragon and the modem that will hold the phone numbers he wants to call so he can select them and set up Dragon to recognize commands for selecting a number and placing and answering calls. You might be able to do that with standard Windows telephony software. I haven't done anything with voice on the Zoom modem but I'm pretty sure the modem will handle it. You will need to check that.

It looks like the Zoom package comes with computer call answering software now so they might have something for placing calls also.

You need a softphone interface modem that is voice enable. Most if not nearly all...are not. The ones that are cost about $50+. You get that modem...you can use the softphone feature. Otherwise you need a desk phone with a handset and a cordless wont work.
