[SIPForum-discussion] Privacy header for Anonymous calls (Remote-Party-ID Header)

[Athar Waqas]

Hi Shakil
Well lets see ur asking whats the URI thing doing in the privacy header...
simple answer to this is when you have to hide the callerID number and send
your own number from the GW then the privacy header is set to URI.
You do not necessarily include the From URL in the Remote-Party-ID. What you
include is identity information for the calling party which may or may not
be the same (if you want privacy, you obviously don't include your real
identity in the From header field, since the From header field cannot be
changed). You can put anyting you want in a From URL, but not in a
Remote-Party-Id.

In your case

Remote-Party-ID: <sip:7026668880 at 8.4.7.6:5060>;*privacy=uri*

Anonymity: uri
in this scenario, the sip/isup gw will use one of its own phone numbers as
the calling party number and that number needs privacy, not the original
from uri:<sip:7026668880 at 8.4.7.6:5060>

You do not necessarily include the From URL in the Remote-Party-ID. What you
include is identity information for the calling party which may or may not
be the same (if you want privacy, you obviously don't include your real
identity in the From header field, since the From header field cannot be
changed). You can put anyting you want in a From URL, but not in a
Remote-Party-Id.

There is no such requirement. In fact, if you have requested privacy, you
are almost guaranteed that the two will be different.

I hope i have been as simple as i can be but if you need anyother
information please do get back.
