Hi Tolga, as a matter of fact there IS a standard for this for the cell phone. I think the idea is not so absurd.
We cannot stay with the solution that the user must use a web browser to do this: It is neither practical with hard phones nor with the majority of non-techy-savvy users. There must be a way that the phone tells the proxy/registrar. CPL would be a possibility. But honestly, I am starring at this document with my mouth open. I don't really think a phone should compile such Java scripts (oh sorry it's just XML). Maybe someone can prove this stuff is a Turing machine. Where has the pragmatism of SIP gone?
