"Hello,
Thank you for contacting our support team.
We've recently changed the privacy settings on our server so fring users will not be able to receive calls and chats from users that are not on their contact list.
This was done to prevent spam messages appear on your handset.
We realize that spam on the handset is much more annoying than on the PC and we do our best to fight that. Saying that, we know that it is also not comfortable when genuine calls from people you know are also blocked.
At the moment, the only way to get around this is by adding the contacts as friends on your contact list on the PC and then open fring. We are working to improve that and apologize for the inconvenience.
Also, for your information - we transfer your user name and password as 'they are' to Skype's servers. Therefore, if you get a 'login failure' message you should check your Skype user name and password on Skype's website.
If you have further queries, please do not hesitate to contact us again.
Thank you,
Vadim
fring support team. "
