I am trying to make a kamailio script which gets a uri from the database and then directs the call to that uri. Setting the uri with a string (not derived from the database) works just fine:

append_branch();

seturi("sip:user@domain");

But I can not seem to pass anything to seturi other than a string. Here are some examples:

$var(branch_uri) = $dbr(ra=>[0,0]);

append_branch();

seturi($var(branch_uri));

# kamailio won't even start when I try to pass the uri from a variable

$var(branch_uri) = $dbr(ra=>[0,0]);

append_branch();

seturi("$var(branch_uri)");

# treats the "$var(branch_uri)" as a literal string -- does not evaluate to the the value of the variable

$var(branch_uri) = $dbr(ra=>[0,0]);

append_branch();

seturi((str)$var(branch_uri));

# kamailio won't start with this syntax inplace

The errors that kamailio gives on start up when I have a variable in passed into seturi are as follows

0(16145) : <core> [cfg.y:3567]: yyerror_at(): parse error in config file /usr/local/kamailio-4.0/etc/kamailio/kamailio.cfg, line 647, column 12-27: syntax error

0(16145) : <core> [cfg.y:3570]: yyerror_at(): parse error in config file /usr/local/kamailio-4.0/etc/kamailio/kamailio.cfg, line 647, column 28: bad argument, string expected

0(16145) DEBUG: <core> [sr_module.c:674]: find_mod_export_record(): find_export_record: found <sl_reply_error> in module sl [/usr/local/kamailio-4.0/lib64/kamailio/modules/sl.so]

ERROR: bad config file (2 errors)

I also tried to accomplish this

append_branch($var(branch_uri), "0.0");

t_load_contacts();

t_next_contacts();

# No errors but didn't work

I found a way around the problem by making a perl script to allow me set the uri:

Perl script:

sub rewrite_uri {

my $m = shift;

my $uri = shift;

$m->rewrite_ruri($uri);

return -1;

}

Then I call it like this:

$var(branch_uri) = $dbr(ra=>[0,0]);

append_branch();

perl_exec("rewrite_uri", $var(branch_uri));

# this works

So I have a viable work around but it seems like there is probably something simple I am missing which should let me accomplish this with out having to do a call into perl.

Any advice any one can give me would be greatly appreciated.
