[SR-Users] possible bug on {param.value,name}

[David Villasmil]

Not really, the question was about

$var(conid) = $(hdr(Route){uri.param,wsconnid})

which returns an extra ">" from:

Route: <sip:10.231.32.37;r2=on;lr;wsconnid=13>

if i print $var(conid) i would get:

May  3 19:24:45 ip-10-231-32-37 /usr/sbin/kamailio[10015]: ERROR: <script>:
WS Connection ID 13>

But then prepending {uri.param,wsconnid} with {nameaddr.uri} and adding {
s.int} did the trick, like so:

$(hdr(Route){nameaddr.uri}{uri.param,wsconnid}{s.int});

Now I understand adding {nameaddr.uri} would basically remove those "<" and
">" and that's why it then works.

Thanks Daniel and Ovidiu,
