Even if flat rates are included in most landline tariffs nowadays, you can often only make free calls within your own network. Calls to other providers' networks or to non-EU countries are a different story. Voice over IP (VoIP), is ideal here; Your voice data is sent to the person you're talking to via the existing internet connection.
