Hello Alex,

Can't test it right now, but it should work better with this :

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

You want to substitute (only affects $var) the whole via header with the regex found between () and referenced by \1. Keep in mind that Daniel's solution is more elegant and should work for you.

Marius hi,

Thank you for your replay.
With the regular expression you provided me I get "SIP/2.0/UDP 172.16.0.13:5060;tgrp:TNDEM-ACR"

Can I isolate only tgrp:TNDEM-ACR ?

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/});

Cheers,
Marius
