Hello all,

I'm trying to test the play_and_get_digits variable from here:

<action application="play_and_get_digits" data="1 1 1 3000 # '' silence_stream://250 dtmf_get \d 3000"/>

Like this:

 <condition field="${dtmf_get}" expression="^$">

But it's always false...

How can I test for an empty (null?) variable?

Regards,

David Villasmil
