I don't think you can do this.  I've never heard of a way (nor have I ever heard anyone else ask this question or one remotely like it, which suggests it's not a popular thought or one likely to have a resolution you'll like).

The only way I can think of that MIGHT work is if the USB Modem is supported by a VoIP PBX like Asterisk.  If so, then you could configure Asterisk to use the modem as it's interface to the plain old telephone system (POTS) and install a VoIP client that would allow you to interact with the Asterisk server and place calls.  

It would be cheaper and FAR less of a hassle (and FAR FAR more likely to work) to simply add a cheap phone and a splitter.
A modem will not be able to do this for you.
You can use asterisk hardware, there are fxo modules you can buy.
The below is the easiest thing and does not require a pc to be turned on 24/7

There are modems that support Asterisk - I have two.  I don't use them, nor are they USB, but they exist.  (maybe they support another tech that I'm not familiar with that enables the support).

This can be done with one of the many PCI modems that incorporate audio drivers.  Many of them use the AC '97 audio standard.  Here are a few of them on fleabay:  Modem 1, modem 2.

However, I've not seen a USB modem that's audio capable.  If your USB modem is audio capable, there should be a "modem audio" device located under "Sound, video and game controllers" in the Device Manager under Control Panel.  If there is no modem audio device, then you'll need to look for a different modem.

with an fxo module you would want one that has caller-id.
Do you have any reason why you want to answer the phone on a pc.

I don't know if this will be a viable workaround for you, but I just saw that Gmail will now let you make phone calls.

Other than that, I'm with totallytonto, as the only method I know of.
