Hi guys,
I'm having a weird situation when trying to modify some parts of the
RPID on my config file. I'm using Kamailio 1.5.3-notls
The code is the following:
...
subst('/^Remote-Party-ID:(.*)sip:(.*)@(.*)$/Remote-Party-ID:\1sip:$avp(s:ANIegress)@\3/ig');
subst('/^Remote-Party-ID:(.*)"(.*)"(.*)sip:(.*)$/Remote-Party-ID:\1"$avp(s:ANIegress)"\3sip:\4/ig');
...
With the first line I'm trying, to change the user part of the SIP-URI
to the value in $avp(s:ANIegress).
Then i just replace the token between double quotes (if any) with the
value in $avp(s:ANIegress).
But when I check the captured (ngrep) results I have the following:
Before:
Remote-Party-ID: "60911000"
<sip:541160911100@192.168.200.100>;privacy=off;screen=no.
After:
Remote-Party-ID: "60911000"
<sip:1160911100@192.168.200.100>;privacy=off;screen=no.Remote-Party-ID:
"1160911100" <sip:541160911100@192.168.200.100>;privacy=off;screen=no.
Can anyone point me on the direction to solve the issue, or a better
way to replace the values in RPID, PAI (and possibly From Header for
some providers)?
Thanks in advence!

Uriel,
Why not simplify the matter?
1. Extract the value(s) of the existing Remote-Party-ID header using
$re.
Or, if you need something other than the RPID URI, some transformation
applied to $hdr(Remote-Party-ID).
2. remove_hf("Remote-Party-ID");
3. append_hf("Remote-Party-ID: <whatever you like!>");
:)

Alex,
Takes a little more work but works perfectly. Thanks!!!
I have to be aware of calls that have 2 RPID headers (party=called and
party=calling), is you're interested I can paste the code once I'm
done coding and testisng. :)
Rgds,
Uriel

Yes, but a lot easier to read, understand and modify from a code and
business process management perspective.

(party=called and
party=calling), is you're interested I can paste the code once I'm

Sure, example code is always good for posterity.

Hello Uriel,
just noticed one small thing:
$avp(s:oldPAI) = $(hdr(P-Asserted-Identity));
There is some shortcut PVs for this header, i think its $pa. Maybe its a bit
cleaner this way. I did not checked, but maybe there is also one for remote-
party-ID which you use as well.
Cheers,

Hi Henning,
I'll try using $pa if it is available. With $re I vave the issue on
some gateways that send 2 RPID headers (one for called and other for
caiiling party).
Cheers,
Uriel
