[Freeswitch-users] Stupid question ;-)

[patrick]

I have some var:
<action application="set"        data="input_fail_counter=0"/>

And in some moment I want to increase it by 1. I try this way:
<action application="set"        
data="input_fail_counter=${input_fail_counter}+1"/>
And have result input_fail_counter=0+1  i.e. just string merge...

How to handle it right way in dialplan?
