string If drop_dtmf is true, play specified file for every tone received.

<action application="export" data="drop_dtmf=true"/>
<action application="export" data="drop_dtmf_masking_file=/etc/freeswitch/Sounds/dtmf_masking_tone"/>

<action application="export" data="nolocal:drop_dtmf=true"/>
<action application="export" data="nolocal:drop_dtmf_masking_file=/etc/freeswitch/Sounds/dtmf_masking_tone" />
