Hello

This example play conf-pin.wav and wait DTMF.

<extension name="play_and_get_digits example">
  <condition field="destination_number" expression="^(1888)$">
    <action application="play_and_get_digits" data="2 5 3 7000 # $${base_dir}/sounds/en/us/callie/conference/8000/conf-pin.wav /invalid.wav foobar \d+"/>
    <action application="log" data="CRIT ${foobar}"/>
  </condition>
</extension>

Is it possible to play WAV file in infinity loop and wait user DTMF?

And how can I check DTMF input after user entered DTMF?

In dialpeer, like.
If ${DTMF} = 1 then bridge to XXX
If ${DTMF} = 2 then play file and finish session



Thank you.
Dmitry
