Step1
Research free computer telephony software products on the Internet such as Skype and iCall. Look for products that have options you are interested in such as voicemail and call-forwarding. Make sure your computer has the suggested system requirements for compatibility with the VoIP phone software.
Step2
Download and install the telephony software. Follow the setup instructions. Most programs walk you through the setup. You may have to register an account username and password.
