title: How do VoIP services connect to landlines?
body: <p>How do VoIP services, such as Skype and Yahoo, connect to landlines?</p>
  
  <p>We have a server connected to a landline using asterisk, so I'm thinking this server will bridge our VoIP conversation and connect it to a landline. </p>
  
  <p>But if this is the case, wouldn't Skype need a lot of servers placed around the whole world just to connect to landlines?</p>
