Very few modems are able to work this way even if you have the software to
do this. Best bet is a special usb phone or a phone adapter that connects
your phone to the internet without a computer. Digium modem cards and
asterisk is the reason the answer is not "no". This is way more than most
people want to do and adapters/usb phones can be found for less than $100
usd.

If it's a regular telephone then you need to use an ATA device. This
provides a 'dial tone' to a regular telephone. Also know as an FXS port.
They're generally around $90. Others can be had that will connect an old
phone to the USB port of a PC. These are around $50 but require the PC be
running to use the phone, whereas an ATA is stand-alone.

A 'old dial up modem' has little use for VoIP activities.

The headset about 600 ohms should work ok on the soundcard but the mic if
carbon element may need some matching.

This has some good ideas:
