 |
|
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 Villasmilemail: david.villasmil.work@gmail.com (david.villasmil.work@gmail.com)

As I remember, the empty value of a variable is equivalent of unset variable. So, I think you can't test variable if it is empty at all
