Skype Forwarder uses a voice modem as a gateway between the Skype network and your telephone provider, forwarding in both directions. Skype Forwarder also will provide full answering machine services for the gateway, saving both phone and Skype messages if needed. Skype Forwarder is simple to install and transparent to use. If it successfully detects your modem you add your Skype contacts to your extension list and forget about it.
