What command do I type to capture details pressed in an IVR

[eman]

<action application="set" data="answer2=${ivr_digit_pressed}"/>
<action application="log" data="INFO Captured answer2 (digit pressed): ${ivr_digit_pressed}"/>

<action application="set" data="answered_by_ext=${last_bridge_to}"/>
<action application="export" data="answered_by_ext"/>
<action application="log" data="INFO Captured answered_by_ext: ${answered_by_ext}"/>

CURRENTLY, I HAVE THIS SET, BUT I still can't capture THE DIGIT PRESSED ON MY IVR


PLEASE ASSIST IF POSSIBLE AND THANK YOU IN ADVANCE.
