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

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!>");

:)

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

Here it comes.

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

Sure, example code is always good for posterity.

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

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,

Henning
