I am writing custom dialplan to excute sheel script using system application. when i write this code it runs fine

<action application="system" data="myapp.sh"/>

but as mentioned in https://freeswitch.org/confluence/display/FREESWITCH/mod_dptools%3A+system url when I write dialplan <action application="set" data="OUT=${system foo.sh}"/>

it does not run.

What I want to is to save the output of the script in a variable and to use it in dialplan.

Please let me know if i am doing anything woring or any help which can help me to achive this.

Thanks

Answer 1

try this it should work

<action application="set" data="OUT=${system(myapp.sh)}"/>

make sure there is no space between "system" and the "(" opening bracket
