5 thoughts on “The Skype Controversy Continues”

  1. Om…I very much appreciate your comments and enjoy the discussion. My piece created much more dissension than I ever thought it would…not that this is a bad thing. The debate is strong…this can never be did.

    One point though, I did not infer that the only reason I thought that Skype was abusing the VOIP moniker was because they do not have “SIP gateway”. In fact, those points were made in the reverse order than that which your reader communicated them or you listed them. A small but important point I believe.

    There are a number of reasons why I disagree with the characterization of Skype as VOIP. But, as I point out in my piece, Skype is in the technical sense of the term voice traveling over TCP/IP. However, the lack of the SIP client /server infra is not the only reason why I wouldn’t characterize it as VOIP in the biz sense of the term.

    In general I am pointing out a nuance here and trying to highlight the differences between true VOIP carriers such as Vonage, and Skype, which I am sure you recognize.

    BTW, you make an excellent point in the distinction between the encryption of the call and of the call setup / patterns. I’d be very interested to hear how Skype responds to this.



  2. if skype uses the internet, then by definition it’s voice over IP (Internet Protocol)..end of story.

    The argument is; should voip should be a tag for all voice over internet protocol mechanisms?

    Some people, (Greg Scher maybe?) believe that VOIP is a standard using SIP to set up point to point calls using a network. Whereas skype uses a p2p style connection and therefore isn’t truly following the voip standard to the letter.

  3. I reread the original article by Greg. I am still missing the difference between “true” VoIP providers like Vonage and Skype. It can not be that Skype is not using SIP (as Rob suggests), for AT&T does not currently use SIP; probably Cablevision and TW use PacketCable from CableLabs. Probably the point was simply that Skype is a proprietary protocol. I would appreciate if Greg or somebody shed light on this.
