---------- Forwarded message ---------- From: YannUbuntu <[email protected]> Date: 2010/5/27 Subject: Basic questions on P2PSIP To: [email protected] Dear all, I am new on this mailing-list. My name is Yann, I am a simple Ubuntu linux user (and volunteer), who tries to understand and help improving free software for videoconference. Let's say, on Ubuntu I use Skype for videoconference (webcam+audio+chat) with Ubuntu and Windows users, it works pretty well, but it is closed-source, so I am trying to find a free alternative, or help making it. I have very basic knowledge about P2P and internet communication, so please correct me if I am wrong for all the following. As far as I know, the two best protocole alternatives are SIP (via Ekiga for example), and Gtalk (via Empathy for example), but with these I still could not get results as good as with Skype. I have been told that Ekiga is sometimes blocked by firewalls/internet boxes, and that Skype, Windows Live Messenger and Gtalk don't have such problem because they use "http tunnel" (Skype), Google servers relay (Gtalk), or "non-standard P2PSIP" (WLM). So I wonder if it could be possible to do the same with free SIP softwares such as Ekiga ? I understood that the purpose of P2PSIP is to create a "P2PSIP standard", am I right ? what is the current status of P2PSIP project ? what are next steps ? where do you most need help ? I saw many propositions on the website (http://www.p2psip.org/implementations.php), where can I find a comparison (advantages/disadvantages) between them ? do you work on all of them at the same time ? Which one is the "best" ? If a free SIP software (e.g. Ekiga?) choose this current version of the "best P2PSIP protocole" in order to enable P2PSIP between all Ekiga clients, would it be possible to do webcam+audio between 2 Ekiga clients even with firewalls/internet boxes, the same way that Skype now does ? If not, when do you estimate this "best proposition" can become reliable enough to be used by SIP softwares ? Thank you in advance for your answers.
