Is there any free software which is making my computer works as a telephone ?

send/receive calls
working as an answer machine
waiting servise
showing caller id
etc........

using a telephone line
i have a fax modem installed in my pc

I am assuming that you are referring to using the computer as phone line itself
Not attached to a phone line
The technology is called voice over ip
Various services
Easiest to use is skype

You will, of course, have to pay a (very small) fee in order to make and receive calls from a traditional phone.


EDIT: In response to the post above me:
Skype is NOT free software. It is freeware.
