vCARD is OK. I have asked a SIP question (I think this is the right place). Please answer my question about SIP trapezoid, or if you don't know, that's OK. As for your proposal for using Bluetooth or IrDA (discussion topic for humanresolvers ML), this is of course a point of view. But I think you missed the point. This is clearly an IP layer problem and technology independent. Why not use Wi-Fi? or WiMax? Why not use the Internet? You really don't see the benefits? /a > > Pars Mutaf wrote: > > > > > > On 10/12/07, *Spencer Dawkins* <[EMAIL PROTECTED] > > <mailto:[EMAIL PROTECTED]>> wrote: > > > > > The privacy problem: normally I shouldn't be able to discover > > your SIP URI. > > > > I'm guessing that if you can't tell people your SIP AOR, then SIP > > is not for > > you. > > > > > > Hello, > > > > I won't publish my SIP URI in a phone book allowing anyone to see it. > > We already agreed on that. > > > > I'll tell it to people that I know only.
