I use my mobile, dual-sim with 2Degrees for Business and Vodafone for personal, My Uniden cordless hooked up to a PAP2T via 2Talk and Skype for free video calling!
If I had an iPhone/iPad I probably would try it - More likely to try it with an iPhone as I can't see anything other then group calling being very good on an iPad!





I would try Time to Call if it was cost effective and easy to load credit onto (i.e. simpler than Skype). I have naked DSL and I very occasionally use skype.
