To my knowledge, phonebook users never complained about that. The real problem of the phonebook, today, is the privacy problem. An extension is needed for interactive user permissions as stated by Adam Roach. A note about name collisions: Similarly to a traditional phonebook user, if you are looking for a certain John Smith, hopefully you will have some additional information helping filter the results. (in the proposed extension, the target cell phone may return such information, e.g. company name, street address, etc.) Note also that if anyone can send you a resolution request, that is > roughly equivalent, in terms of intrusiveness, to anyone causing your > phone to ring. The proposal is rather as follows (abstract): You solve to a challenge (e.g. a CAPTCHA) to obtain the target phone number. Then, you can make a call, send a message etc. Thanks, pars Alternatively, if you want a challenge / response on the resolution > request, you can give a challenge / response on the SIP request. > > Yours, > Joel > >
