I assume you really know too little about "real" 3g video calls which are not running on IP. In any case, you are not interested at all about this issue.
Why do you bother giving comments on this issue ?
We (who really needs 3g video calls over the carrier) are trying to discuss why we don't have this feature and how we can get it.
If you want to make comments, I have 2 suggestions to you:
1. Find yourself 2 phones and a carrier which supports 3g video calls (such as a Nokia E71), make a "video" call from one phone to the other one without installing any software like Fring.
2. Read a little about H324. For example : http://en.wikipedia.org/wiki/H.324
For your referance:
H.324 is an ITU-T recommendation for voice, video and data transmission over regular analog phone lines. It uses a regular 33,600 bit/s modem for transmission, the H.263 codec for video encoding and G.723.1 for audio.
