Hi Pasan,
That is really weird I would say. Could you "pack" the minimal script to
get this error (plus the pcap of the REGISTER) ? you can send them off
list to me.

Hi Bogdan,
I tried scrip_trace function and it also indicate same behavior, I can
see the value of $tu but it still gives the error. Interesting thing
is, it evaluates to true and invokes the remove() function as well.

Hi Pasan,
Indeed, the logs show that the TO hdr is successfully parsed - are you
100% sure about the reported line ? maybe it is not the $tu related ?
try to activate the script_trace()
[http://www.opensips.org/Documentation/Script-CoreFunctions-2-4#toc42]
function to see when exactly the error is generated. Maybe you can
actually print $tu before, to see what you get.

Hi Pasan,
It should be fine if $tu would translate to NULL. The script handles
this case. But I'm afraid you have something else there, like another
deeper error that prevents the $tu variable to be evaluated.
Do you see any other errors before the mentioned ones ? what is the
type of route where you do the test ?

Hi Guys,
I have a check for NULL for $tu var in the script, But when the
value is missing I'm getting the following error.
ERROR:core:comp_scriptvar: cannot get left var value
WARNING:core:do_action: error in expression at
/etc/opensips/opensips.cfg:806
and line 806 contains following.
if ( $tu != NULL ) {
remove("location","$tu");
}
any suggestion on how to test for NULL values without getting above
error. I'm using opensips 2.3.5
