Hi -- Sorry if this question isn't as advanced as the rest of the questions, but I don't see anything about posting guidelines in your faq (which I also don't see).
In general, I am looking for some info about SIP / VOIP 'free calls.'
In specific, I'm looking at IdeaSIP 'free' telephone calls from pc to pc. They seem less hype-ey than the other services and say that they are ad free, spam free, etc.
My question to you is, how can they offer 'free' pc to pc phone calls? Is it really ok to use these services? How do you find a reliable one?
THANKS for any info,
BK, voip-curious.
