[OpenSIPS-Users] check for NULL values

[Bogdan-Andrei Iancu]

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 ?

Regards,
