anyone here using voipbuster.com , voipstunt.com ?
how is the quality ?
Those two are part of the betamax group I mentioned in the post directly above yours.
My experience with their services:
For calls to Europe and North America, fantastic.
For calls to Australian landlines, so-so. For calls to Australian handphones, crap.
For calls to Asia, lousy - because the latency ends up being so high that echo cancellation can't work and there is an annoying delay.
When I am traveling outside of Asia, I use it to call back to Malaysia and that works fine. Also I use it to make my European and US numbers ring on my Digi phone, and that works fine too. It's just Malaysia->Asia calls that suck.
