[Sip] draft-ietf-sip-history-info-01.txt

Dear all,
in 1.3 Ensuring the Privacy of History_Info it is proposed to use a priv-value of Session or Header level privacy. I would like to propose a own privacy level for the history info, because the Information shows also information about the network. With regard to the provider operating a network some of the providers don't like to transmit information about call history. Or a redirecting party don't like to show the redirecting address.
Therefore it should be possible to delete the history info at domain boundaries based on the privacy-value.

I propose the priv-value   =   "history_info"  for the whole History-Info header.

In addition a option would be useful where only parts (e.g Indes1.1) of the history info are restricted. That could be done with a privacy statement within the History-Info .

Best Regards

Roland
