Hi 

I tried the binary operation using $var as per the documentation and its seems not working. Can somebody help me to understand it.

http://kamailio.org/dokuwiki/doku.php/pseudovariables:3.1.x

$var(a) = 3 + (7&(~2));

if( [ $var(a) & 4 ] ) {
  xlog("var a has third bit set\n");
}

The format with square bracket in the conditional statement is showing parse error when i load the cfg. So it tried like below and that too not working 

$var(a) = 8;

if( $var(a) & 4 ) {
  xlog("var a has third bit set\n");
}
Please let me know if something missing here.?


Thanks
Jijo
