Paul; Are you suggesting to include three hi-entries, whenever an entity retargeting the tel-URI logs it to H-I? e.g. History-Info : <tel:2222222>;index=1 History-Info : <sip:{sip representation of tel URI}>; index=1.1; mp=1 History-Info : <sip:{retarget URI}>;index=1.2, rc=1.1 (based on the new semantics Hadriel suggested) In that case, how do you think the privacy of the tel URI should be handled? Should the proxy apply the same privacy policy that it would apply to the SIP URI?

I guess its lucky that if you do create H-I entries for this, that its the translated (sip) URI that gets the parameters added. So its at least *possible* to do this. > > Thanks, > Paul
