With 2008 coming to an end, the best free voip services is something we wanted to review for 2008.  With plenty of free voip available in 2008, which services were your favorite?  These are our top voip service picks for 2008.

1) Betamax – One of the cheapest free voip companies around.  As a user of Justvoip from betamax, I often make free calls to the USA.

2) Skype – Since most voip services don’t allow you to call toll free numbers without buying credit, we recommended Skype as one of the best for making free toll free calls with zero credit on your balance.

3) Tringme – the new face of the Indian voip services.  Extremely popular with Indians.

4) Rebtel - One of the best for mobile phones to make free voip calls.

All services do and have offered completely free calls and for offering great service in 2008, we’d recommend giving all four of these voip services a chance.
