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 :
or
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...
