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?
according to dialog matching in RFC3261, this should be ok,
but
somewhere is a mention about backward compatibility with rfc2453, where
the from should not be changed.
However, if you have only rfc3261 endpoints, then you are safe to change
the From, if not, try uac module, as it does automatic replacement and
recovery.
Cheers,
Daniel
