[SR-Users] VIA header x-route-tag

[Marius Zbihlei]

Hello 

I think you should try:

$sel(@via[1].params[x-route-tag])

Daniel hi,

When I'm trying the bellow I get the following error:

Dec  1 10:06:17 opensips1 kamailio: ERROR: <core> [select.c:149]: parse_select: invalid index, no closing ]
Dec  1 10:06:17 opensips1 kamailio: ERROR: pv [pv_select.c:45]: invalid select name [@via.params[x-route-tag]]
Dec  1 10:06:17 opensips1 kamailio: ERROR: <core> [pvapi.c:550]: pvar "sel" has an invalid name param [@via.params[x-route-tag]]

I also added an @ before the via

if (search("x-route-tag"))
        {
                $avp(s:xroutetag) = $sel(@via.params[x-route-tag]);
                xlog("----- We have a x-route-tag in the SIP msg avp: $avp(s:xroutetag) -----");
        };


Thank you
Alex

Dear All,

We have some cisco gw that they send to the Kamailio in the first invite and inside the VIA header an x-route-tag="The Gateway that the call entered".

I'm trying to add this to the acc module in order to have it recorded but without sucess.
My config is this:

if (search("x-route-tag"))
        {
                avp(s:xroutetag) = $sel(@via);
                xlog("----- We have a x-route-tag in the SIP msg avp: $avp(s:xroutetag) -----");
        };

I'm trying to add the VIA header to an avp so I could manipulate the string but i cannot implement this.

Does anyone can suggest a way to add the x-route-tag value to an AVP?

Thank you in advance

Alex

sample VIA header:  Via: SIP/2.0/UDP  10.0.0.15:5060<http://10.0.0.15:5060>;x-route-tag="tgrp:TANDEM-KOR"

Hello,

You can use transformations http://kamailio.org/dokuwiki/doku.php/transformations:3.1.x . This should to the trick: (careful on needed modules)


$var(s:xroutetag) = $(hdr(Via){re.subst,/x-route-tag="(.*)"/\1/});




just as alternative, in this case it should works also with selects variables, you can try:

$sel(via.params[x-route-tag])

Cheers,
Daniel
