Daniel hi,

Now it works!
I'm adding in the rpid avp the value that the RFC it says $avp(s:rpid) = $fu; and then

append_rpid_hf("$fU", ";party=calling;id-type=subscriber;privacy=off;screen=no");

In this way I see the headers added correctly in sip message. Considering what you said about the from header make it anonymus that is right! Even in our network we have a switch which din't understand rpid and we change the from to anonymous. In Kamailio the $fu and $fU are writable. In this case how can I change that ?

Thank you

Alex

Hi Daniel,

What i want to implement is when a call comes with an avp=1 then this call should not present the calling number. From examples I saw it looks like I need to add an extra header, with :
append_rpid_hf("sip", "$ru;party=calling;id-type=subscriber;privacy=off;screen=no");

I don't understand for what stands the rpid even I'm reading about it:

The SIP Remote-Party-ID header identifies the calling party and includes user, party, screen and privacy headers that specify how a call is presented and screened.

I mean what value I should add in subscriber table if the call is coming from an IP address and from a particular number?

I'm loading now the rpid:
modparam("auth_db", "load_credentials", "rpid")
but I don't understand how it works :-(
do you have something in the column 'rpid' of subscriber table for caller record?

However, with the example above of what you want to try, you add request uri in the RPID, which is destination not caller (it is called party not calling party).

If you just need to take calling number and add it to RPID, try:

append_hf("<$fu>;party=calling;id-type=subscriber;privacy=off;screen=no\r\n");

You do not need values in subscriber table. Beware that RPID works only with some gateways, if you need full privacy, is better to replace the from URI with anonymous.


Cheers,
Daniel
