IT'S ALL TRUE !!!
Using YM 7.5.0.333 Beta I've just signed up for what they seem to call "Yahoo Voice", which incorporates "Phone Out" and Phone In".
No mention of the old Net2Phone any more - I just dealt direct with Yahoo, put US$10 in my phone a/c with credit card, and ready to go.
THEN SIMPLY right-clicked a (offline) friend on my YM, selected "Call a Phone #", then for her I selected "Call Home" (I've already put her home # into her Contact Details) - and when she answered I actually talked to her from MY PC (YM) direct to HER telephone.
And the total cost, for that 2 minute call, from here in
New Zealand to USA - US$0.02, yup, just
1 cent/minute!! (I've since checked, and indeed my balance is now down to US$9.98).
Yahoo - I'm proud of you - let's see Skype overcome THIS sort of opposition !
(The only "odd" thing was/is, when I click to check my a/c balance etc, it takes me to a Yahoo-Argentina page! Oh well, outsourcing works, I guess - all my info was there ok ;) Si, Senor. )
