[Kamailio-Users] How should I change Calling Party Number for a call?

[Uriel Rozenbaum]

Hi Guys,

I was wondering how can I implement a proxy with Kamailio that can manage
privacy and normalization of the calling party.

In an INVITE message I can get the calling party name (or number) in several
places:
1. From Header
2. Remote-Party ID
3. P-Asserted-Identity
4. P-Preferred-Identity

How should I act in order to normalize or block the Calling Party to be
passed to subsequent hops?

AFAIK I can change the From Header as long as the tag isn't modified. Is
this really true?
What about RPID or PAI? Should I Change the aliases there as well?

Thanks in advance to all!

Uriel
