            Great application! Wote 10 for this project. But... I can't install the program on Windows XP. The system shows me the error message: "Invalid authentication attempt". On Linux runs without any problems!

            Basically, SIP and RTP are only two of the numerous protocols relying upon IP. So 'internet phone' would be adequate.


            However, SIP is an HTTP-like protocol. This means that SIP messages look very much like HTTP messages. Incidentally, SIP addresses (the address at which an individual could be reached, btw, I should say SIP URI) look like http addresses, eg :

            sip:duponddupont@moulinsart.com

            or

            sip:0123456789@france-telecom.com


            SIP applications and devices exist already. The next expected step is to integrate SIP devices in the home network, so that SIP adresses could be transmitted in e-mail or on web pages, and a browser click on the adress would activate the SIP device (or PC conferencing application), just as a click on a sound file nowadays runs the media reader.


            So, hopefully, this application WILL become a webphone, without any modification since the evolution is then in the browser and network management...
