I'm really confused on how this work, so I apologize.
I created a Fring account and added my skype on my Evo. Then I installed skype on my macbook. I added my EVO phone number to my skype on my mac and when I tried to call my EVO through my Mac, it said I needed to buy credits.
How is this supposed to work?
Fring EVO -> Skype Desktop?
Skype Desktop -> Fring EVO?
You're into the Skype features you don't want - and it's easy to fix.
Skype does four things:
* text messages to other Skype accounts
* audio chat and audio conference to other Skype accounts
* video chat to other Skype accounts
* access to phone lines outside of Skype - this is the only part that costs money
So - you have a Skype account, you entered that as your login for Skype under Fring. Correct.
You added your phone number as a buddy under your desktop Skype - not correct. That will take you to the part of Skype that lets you make phone calls - you don't want that.
Skype is pretty good about not letting you conference with yourself.
Get a buddy, share him as a skype buddy from your desktop and his skype - Add Contact, send invite.
Now, go to fring on your phone - you'll able to see him in your buddy list and you'll be able to audio or video or text with him - for free.
And I've found the quality between my phone and Skype desktop to be quite good.
My co-workers jealously report me as coming in clear as a bell.
I've been using it without trouble since getting my phone on 6/6 - hope this helps.
