Hello,
you have to use it only once -- this is due to how the changes are done
to the sip message headers, but also because of adding a special
parameter to record-route header. It is its well known behavior since
more than 10 years ago.
Wait until you know what is the final version of the header that should
be sent out and then change it. Before that, you can keep it in a config
variable that can be overwritten easily.
Cheers,
Daniel

Apparantly it should be simple to mangle the From in
request:
http://kamailio.org/docs/modules/stable/modules_k/uac.html#id2525538
The task at hand is use the prefix 131 to suppress callerid for this call:
if($rU=~"^131[0-9]+$")
{
strip(3);
append_hf("Privacy: id\r\n");
uac_replace_from("anonymous","sip:anonymous@anonymous.invalid:$rp");
uac_replace_to("","sip:$rU@$rd");
}
Just before this replace there is an other uac_replace_from to rewrite an
alphanumeric username to the default callerid for that device. If there are 2
uac_replace_from in the path, things go wrong like below. A uac_restore_from()
before the second uac_replace_from doesn't change this behavior.
device calls 1310123456789:
U 10.0.34.226:1300 -> 10.0.35.226:5060
INVITE sip:1310123456789@kamailio.local:5060 SIP/2.0.
From: <sip:anonymous@10.0.3.44:5060>;tag=26e5ce5850.
To: <sip:1310123456789@kamailio.local:5060>.
Kamailio forwards request to dispatcher but fails to properly replace the from
uri:
U 10.0.35.226:5060 -> 10.0.32.36:5060
INVITE sip:+31123456789@kamailio.local:5060 SIP/2.0.
From: "anonymous" <sip:
+31987654321@10.0.3.44:5060sip:anonymous@anonymous.invalid:5060>;tag=26e5ce5850.
To: <sip:0123456789@kamailio.local>.
Even though the debug log suggests it did the proper replacement:

and
