whether skype or voipstunt are using SIP protocols. I have experienced that in many countries, where voice ports are blocked by the Telecom providers but still voipstunt and skype works for calling to PSTN.
Please give me some links, for further reading on this.
Don't know about Voipstunt. Skype has an entirely proprietary protocol stack - no SIP, or anything else "open."
