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

[alex pappas]

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]]
Dec  1 10:06:17 opensips1 kamailio: ERROR: <core> [pvapi.c:705]: wrong char
[)/41] in [$sel(@via.params[x-route-tag])] at [29 (5)]
Dec  1 10:06:17 opensips1 kamailio: : <core> [cfg.y:3328]: parse error in
config file /usr/local/etc/kamailio/kamailio.cfg, line 705, column 23-52:
unknown script pseudo variable $sel(@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
