Comment 2 for bug 1207353

Thanks for reporting this issue and help in making Ubuntu better, and sorry for the delay in getting an answer.

Please check the suggestions in:
http://askubuntu.com/questions/310960/how-to-use-skype-with-empathy-in-13-04

There are a couple of methods suggested there to integrate Skype in Empathy. Sorry I haven't tried them so I don't know if they work.
