I do not want to passthrough INBAND dtmf.
How remove (cut) them or may be disable passthrough ?
I found function VOLUME
wiki.asterisk.org/wiki/display/ … ion_VOLUME
Arguments
direction - Must be TX or RX.
options
p - Enable DTMF volume control
But this not work as expected :
$AGI->set_variable(“VOLUME(RX,p)”, “-200”);
$AGI->set_variable(“VOLUME(TX,p)”, “-200”);
