Hello,

things are different that one may expect from evaluation of an expression compared with other established scripting/programming languages. One thing to be sure you are aware of are the return code evaluation:

  - https://www.kamailio.org/wiki/tutorials/faq/main#how_is_the_function_return_cod

To be sure of proper behaviour, you should do:

if(uri =~ "<regex string to match>" || uri == myself) {

$var(myself) =1;

} else {

$var(myself) = 0;

}

Same with is_myself("$ru") instead of uri == myself.

Try and see if you get different values for $var(myself).

Yes, they are used at the very same place. here is a code snippet of where i added it for testing purposes:

route[INIT_VARS] {

$var(myself) = uri =~ "<regex string to match>" || uri == myself;

//if i print $var(myself) it prints 0 

$var(myself) = uri =~ "<regex string to match>" || is_myself("$ru");

//if i print $var(myself) it prints 1 

// in both cases above the regex part isn't supposed to match and hence correctly returns false.

...

}

route{

   route(INIT_VARS);

...

}

Thanks,

Karthik

they are supposed to be the same in this case.

Are they used at the same place in config? Note that $ru can be changed
by different functions such as those from registrar, dispatcher, lcr, ...
