HI Daniel, thanks, so in the first case instead of assigning the value to the $var(x) can i delete the $var(x) so that comparison works ?
in the second case (returned value from transform) what value should i compare against to check if returned value was null ? ________________________________ From: sr-dev [[email protected]] on behalf of Daniel-Constantin Mierla [[email protected]] Sent: Monday, January 05, 2015 3:51 AM To: Kamailio (SER) - Development Mailing List Subject: Re: [sr-dev] need help understanding $null Hello, $var(...) cannot be null by design, setting it to $null makes it 0. $null is more for variables that don't exist, e.g., you don't have the $avp(x), then it is null if you compare it.
