I am trying to use portaudio to bride a radio device into freeswitch.  I
encountered a problem that I believe to be a bug, although I am not
sure, so I am asking if anyone can confirm this.


   <extension name="radio_conference">
     <condition field="destination_number" expression="^123$">
       <action application="answer"/>
       <action application="sleep" data="1000"/>
       <action application="start_dtmf"/>
       <action application="conference" data="radio@default"/>
     </condition>
   </extension>


if I call that from portaudio all input from the microphone appears to
be discarded.  If I call it without the start_dtmf it works as expected.
To avoid any potential for confusion, I do actually need inband DTMF
detection from the radio side of things.


I only looked at this from the portaudio side of things, so if anyone
who has an otherwise working portaudio configuration could look to see
if this is present in their systems I would appreciate it to know if
this is something I did or something else.

Once confirmed I will look at posting a bug report, but I dont want to
do it if its just me.
