[Freeswitch-users] Passing dtmf to an IVR behind Google Voice problem

[Dmitry R]

Hi, does anybody know how to pass dtmf codes to an IVR behind the Google
Voice entrance number? 
A simple example code from http://wiki.freeswitch.org/wiki/Google_Voice 

  <extension name="google_in" continue="true">
     <condition field="caller_id_name" expression="^(Google Voice)$" >
         <action application="log" data="Google Voice Call Incoming" />
         <action application="set" data="execute_on_answer=send_dtmf 1"/>
     </condition>
   </extension>

doesn't work for me. DTMF codes can't get thru. Everything else other then
that works fine.

Any help would be very much appreciated, Dmitry
