Where is this variable getting or losing the "undef" value? Also, add this line to info and see what gets printed: <action application="log" data="WARNING $var contains '${var}'"/> That will print it out in purple letters to make it easier to see. FWIW, I tried this with various permutations of 'undefined' channel vars and expression="^$" always worked for me. -MC On Mon, Jan 17, 2011 at 3:55 PM, Madovsky <infos@madovsky.org> wrote:

Is the var showing up as "UNDEF" when you send the call to the info app? -MC
