| For most VoIP services yes you do need 
      a computer, and definately yes for free VoIP services. Only the 
      specialised paid for services negate the need for a computer. 
       You will still need an internet connection of 
      course but computer-less configurations mean you will need specialised 
      hardware generally in the form of a router. (thats r-ooo-t-er and not r-ow-t-er 
      ;o) please take note!) 
      Business setups (ie mega money) have very 
      specialised routers and switches to handle VoIP calls, usually across 
      their own private networks
