Hello,
I'm trying to change contact header in SIP response message by stripping
first characters (for testing only) as below :
$ct = $(ct{s.strip,25});
But I got below error saying that $ct is read-only:
0(15410) : <core> [cfg.y:3419]: yyerror_at(): parse error in config file
/usr/local/etc/kamailio/kamailio.cfg, line 575, column 5-7: read only pvar
in assignment left side
ERROR: bad config file (1 errors)
The question is how can I change contact header before it's sending of
Kamailio?
Thanks
Ali

Hi Alex,
This is related to post Kamailio LCR Multiple choices I created before, where last gateway
is listed at the first in contact header.
So as I didn’t get a solution from your side regarding this issue , I tried to strip first
gateway from contact header.
Regards,
Ali

Ali,
With the exception of a few, pseudovariables that expose parts of a SIP message (such as
$ct) are read-only, so you cannot assign values to them.
Why are you manipulating the Contact header? This is not something proxies should
ordinarily do.
But, assuming you really want to/know what you're doing:
remove_hf("Contact");
append_hf("Contact: <sip:...>\r\n");

Ali,
That's not going to work, for reasons related to the state of the message body at the
time you're manipulating it. You need to get to the bottom of the fundamental issue:
why are the gateways not in the order you want? And you need to fix it on that level.

Hi Alex,
In contact header I'm getting last gateway is listed first , then gateways are ordered
correctly.
Let's say I have 3 gateways ordered as 1,2,3 in LCR_rule_target table
I'm getting in the contact header : 3,1,2,3
I'm using below code
if (!load_gws(1, $rU, $fu))
{
sl_send_reply("502", "Unable To lOad GatEwAyS");
exit;
}
else while(next_gw())
{
append_branch();
}
sl_send_reply("300","Multiple Choices");
any help would be appreciated.
Ali

Hi Ali,
Sorry, I've never used the lcr module. Whenever we build anything, we just pull lists
of gateways from our own database tables with sqlops, typically using sql_xquery() to
store them in lists of XAVPs and then manually iterate over them.
The lcr/carrierroute/drouting modules just provide wrappers for this kind of process, with
their own table schema and metrics.

Hi Alex,
Thanks for your reply,
Can you please send me the routing script you're using in order to pull the list of
gateways and iterate over them?
Regards,
Ali
