I have to agree with SiB completely. After installing telepathy-sofiasip and keeping the same settings as mentioned in SOLVED section of http://pokazywarka.pl/bug617754/#zdjecie508551, I am able to make my voip account with voipbuster.com work.
In addition to that, I realised you can actually make and receive calls if you put in the STUN server name, in my case it was stun.voipbuster.com; though I have to say that, the whole SIP experience with empathy is far not stable.
At least in my case, I have had to restart empathy several times, so that I will get the incoming calls from the voipbuster client installed on a windows pc. Other times, the I couldn't hear anything from the caller, sometimes the caller couldn't hear anything from my side. I am not sure, whether this was due to the buggy voipbuster client!
