I need to make a lot of long distance calls to very costly destinations. I was using Skype, but I accidentally entered the wrong Verified by Visa password when adding credit. Now for "security precautions" they have suspended my ability to add funds for up to a month. No amount of pleading will change their minds. I tried signing up with Yahoo! (dialpad.com), but their client only runs on Windows XP. Can you suggest any other services I can use?
