Ive downloaded the new version of yahoo voice...asked my relatives abroad also MAC users to download it so we wont be SKYPE dependent. But as we tried it out-we were not able to hear one another OR not connecting properly?...What follows after the attempt to use the YM voice call function is: a voice mail alert EMAIL from yahoo will be sent to me with an attachment of her voice in mp3 format...What causes this? Anybody out there having this same problem? Added info : we have different OS's. I have leopard and she uses tiger. Does this count as one of the reasons why YM voice doesnt work with us? Any help will be greatly appreciated thanks.
